Harvard Dropouts To Launch 'Always On' AI Smart Glasses That Listen, Record Every Conversation 68

Two Harvard dropouts are launching Halo X, a $249 pair of AI-powered smart glasses that continuously listen, record, and transcribe conversations while displaying real-time information to the wearer. "Our goal is to make glasses that make you super intelligent the moment you put them on," said AnhPhu Nguyen, co-founder of Halo. Co-founder Caine Ardayfio said the glasses "give you infinite memory."

"The AI listens to every conversation you have and uses that knowledge to tell you what to say ... kinda like IRL Cluely," Ardayfio told TechCrunch. "If somebody says a complex word or asks you a question, like, 'What's 37 to the third power?' or something like that, then it'll pop up on the glasses." From the report: Ardayfio and Nguyen have raised $1 million to develop the glasses, led by Pillar VC, with support from Soma Capital, Village Global, and Morningside Venture. The glasses will be priced at $249 and will be available for preorder starting Wednesday. Ardayfio called the glasses "the first real step towards vibe thinking."

The two Ivy League dropouts, who have since moved into their own version of the Hacker Hostel in the San Francisco Bay Area, recently caused a stir after developing a facial-recognition app for Meta's smart Ray-Ban glasses to prove that the tech could be used to dox people. As a potential early competitor to Meta's smart glasses, Ardayfio said Meta, given its history of security and privacy scandals, had to rein in its product in ways that Halo can ultimately capitalize on. [...]

For now, Halo X glasses only have a display and a microphone, but no camera, although the two are exploring the possibility of adding it to a future model. Users still need to have their smartphones handy to help power the glasses and get "real time info prompts and answers to questions," per Nguyen. The glasses, which are manufactured by another company that the startup didn't name, are tethered to an accompanying app on the owner's phone, where the glasses essentially outsource the computing since they don't have enough power to do it on the device itself. Under the hood, the smart glasses use Google's Gemini and Perplexity as its chatbot engine, according to the two co-founders. Gemini is better for math and reasoning, whereas they use Perplexity to scrape the internet, they said.

Electricity Prices Are Climbing More Than Twice as Fast as Inflation (npr.org) 238

Electricity prices have increased at more than double the inflation rate over the past year, according to NPR reporting. Florida Power & Light customers face monthly bills exceeding $400 during summer months, prompting the utility to seek a 13% rate increase over four years that drew tens of thousands of petition signatures in opposition.

The Energy Department projects data centers will consume more electricity than residential customers for the first time in 2026. Natural gas costs for power generation rose 40% in the first half of 2025 compared to 2024, and the department expects another 17% increase next year. Natural gas generates more than 40% of U.S. electricity. One in six households currently struggles to pay electric bills. The federal government provides $4 billion annually in energy assistance for low-income families.

America's EV Registrations Rise 7% in 2025 - Giving EVs a 7.5% Market Share (yahoo.com) 247

EV sales are up 27% for the first seven months of 2025 — for the world. But in America "For the first half of 2025, EV registrations rose 7% to 620,642, with market share inching up just 0.1 percentage point to 7.5 percent," reports Automotive News.

America's new EV registrations were up 4.6% in June (compared to June of 2024), "But EV market share fell for the month and stayed flat for the first half of the year, according to the most recent S&P Global Mobility data." June's 113,460 EV registrations represented 8.6% of U.S. light-vehicle market share, down from 8.8% a year earlier... The data, which serves as a sales proxy since some EV makers don't report U.S. numbers, shows continued flattening of EV market share ahead of the Sept. 30 repeal of the $7,500 federal tax credit.

The S&P Global Mobility numbers include only battery-electric vehicles and not hybrids.

In June Tesla led with 57,260 registrations — more than 6x its next competitor. (Although Tesla's share of the EV segment dropped 6.8% to 43.7 percent in the first half of 2025).

Ranking #2 in June registrations was Chevrolet with 9,517 — a 152% gain over Chevrolet's June 2024 registrations. (Pointing out that the Chevy Equinox EV starts at under $35,000, Electrek writes that "America's most affordable EV with over 315 miles of range, as GM calls it, is quickly winning over buyers.") Automotive News reports Equinox EV registrations surged 722% to 6,239 in June, with Chevy's share of the EV segment more than doubling to 7.7%.

Chevy pulled ahead of Ford (5,759 registrations), Hyundai (5,227 registrations), Rivian (4,613 registrations) and Cadillac (4,121 registrations). Although maybe it's just as interesting that the complete chart shows electric vehicle registrations for 33 different automakers...

Seagate 'Spins Up' a Raid on a Counterfeit Hard Drive Workshop (tomshardware.com) 47

An anonymous reader shared this report from Tom's Hardware: According to German news outlet Heise, notable progress has been made regarding the counterfeit Seagate hard drive case. Just like something out of an action movie, security teams from Seagate's Singapore and Malaysian offices, in conjunction with local Malaysian authorities, conducted a raid on a warehouse in May that was engaged in cooking up counterfeit Seagate hard drives, situated outside Kuala Lumpur.

During the raid, authorities reportedly uncovered approximately 700 counterfeit Seagate hard drives, with SMART values that had been reset to facilitate their sale as new... However, Seagate-branded drives were not the only items involved, as authorities also discovered drives from Kioxia and Western Digital. Seagate suspects that the used hard drives originated from China during the Chia [cryptocurrency] boom. Following the cryptocurrency's downfall, numerous miners sold these used drives to workshops where many were illicitly repurposed to appear new. This bust may represent only the tip of the iceberg, as Heise estimates that at least one million of these Chia drives are circulating, although the exact number that have been recycled remains uncertain.

The clandestine workshop, likely one of many establishments in operation, reportedly employed six workers. Their responsibilities included resetting the hard drives' SMART values, cleaning, relabeling, and repackaging them for distribution and sale via local e-commerce platforms.

Virtual Power Plants: Where Home Batteries are Saving Americans from Blackouts (msn.com) 123

Puerto Rico expects 93 different power outages this summer, reports the Washington Post.

But they also note that "roughly 1 in 10 Puerto Rican homes now have a battery and solar array for backup power" which have also "become a crucial source of backup power for the entire island grid." A network of 69,000 home batteries can generate as much electricity as a small natural gas turbine during an emergency, temporarily covering about 2 percent of the island's energy needs when things go wrong... "It has very, very certainly prevented more widespread outages," said Daniel Haughton, [transmission and distribution planning director for Puerto Rico's grid operator]. "In the instances that we had to [cut power], it was for a much shorter duration: A four-hour outage became a one- or two-hour outage."

Puerto Rico's experience offers a glimpse into the future for the rest of the United States, where batteries are starting to play a big role in keeping the lights on. Authorities in Texas, California and New England have credited home batteries with preventing blackouts during summer energy crunches. As power grids across the country groan under the increasing strain of new data centers, factories and EVs, batteries offer a way for homeowners to protect themselves — and all of their neighbors — from the threat of outages. Batteries have been booming in the U.S. since 2022, when Congress created generous installation tax credits for homeowners and power companies.

Home batteries generally come as an option alongside rooftop solar panels, according to Christopher Rauscher, head of grid services and electrification for Sunrun, a company that installs both. More than 70 percent of the people who hire Sunrun to put up solar panels also get a battery. With the tax credits — and the money saved on rising electricity costs — solar panels and batteries make financial sense for most American homes, according to a study Stanford University scientists published Aug. 1. About 60 percent of homes would save money in the long run with solar panels and batteries...

Those batteries can have broader benefits, too. Utilities pay customers hundreds of dollars a year to sign their batteries up to form "virtual power plants," which send electricity to the grid whenever power plants can't keep up with demand. California's network of home batteries can now add 535 megawatts of electricity in an emergency — about half as much energy as a nuclear power plant... [H]omeowners can make thousands of dollars a year lowering their energy bills, selling solar power back to the grid or enrolling their batteries in a virtual power plant, depending on their power company's policies and state regulations. "Over time, you would get the full payback for your system and basically get your backup for free," said Ram Rajagopal, an associate professor of civil and environmental engineering who co-authored the Stanford study.

Chinese State Media Calls US a 'Surveillance Empire' Over Trackers In Chips (reuters.com) 103

An anonymous reader quotes a report from Reuters: The United States' practice of installing location trackers in chip shipments at risk of diversion to China reflects the "instincts of a surveillance empire," China's state-run media outlet Xinhua said in a commentary published on Friday. Reuters reported earlier this week that U.S. authorities had secretly placed location tracking devices in targeted shipments of advanced chips to detect diversions to China, which is under U.S. curbs for advanced chip exports. The Xinhua commentary, titled "America turns chip trade into a surveillance game," cited "reports" that Washington had embedded such trackers, accusing the United States of running "the world's most sprawling intelligence apparatus." [...] In its commentary, Xinhua accused the U.S. government of seeing its trading partners as "rivals to be tripped up or taken down," adding that "if U.S. chips are seen as Trojan horses for surveillance, customers will look elsewhere."

China is About To Launch SSDs So Small You Insert Them Like a SIM Card (theverge.com) 44

A Chinese storage manufacturer has developed a solid-state drive smaller than a U.S. penny that delivers sequential read speeds of 3,700 megabytes per second, according to The Verge.

The "Mini SSD" by Biwin measures 15mm x 17mm x 1.4mm thick and connects via PCIe 4x2, offering 512GB to 2TB capacities. The drive inserts into devices using a SIM card-style tray mechanism and claims IP68 water resistance plus three-meter drop protection. Two gaming portables announced at ChinaJoy will include slots for the drives: GPD's Win 5 handheld and OneNetbook's OneXPlayer Super X hybrid laptop/tablet, both powered by AMD's Strix Halo processors. The Mini SSD outpaces MicroSD Express cards used in Nintendo Switch 2 by nearly four times, though full-size M.2 drives remain faster at up to 14,000MB/s.

Big Tech's AI Data Centers Are Driving Up Electricity Bills for Everyone (nytimes.com) 67

Electricity rates for individuals and small businesses could rise sharply as Amazon, Google, Microsoft and other technology companies build data centers and expand into the energy business. Residential electricity bills increased at least $15 monthly for Ohio households starting in June due to data center demands, according to utility data and an independent grid monitor. A Carnegie Mellon University and North Carolina State University analysis projects average U.S. electricity bills will rise 8% by 2030 from data center growth, with Virginia facing potential 25% increases. Virginia regulators estimate residents could pay an additional $276 annually by 2030.

National residential electricity rates have already risen more than 30% since 2020. Tech companies' AI push requires data centers that consumed over 4% of U.S. electricity in 2023, with government analysts projecting consumption reaching 12% within three years. American Electric Power warned Ohio regulators that without new rate structures requiring data centers to pay more upfront costs, residents and small businesses would bear much of the expense for grid upgrades.

Pebble Time 2 Reboot Gets a Redesign (9to5google.com) 20

Pebble has unveiled the final design of its rebooted Pebble Time 2 smartwatch, featuring a stainless steel body, color accents, knurled buttons, a flat glass display, customizable RGB backlight, and a built-in compass. 9to5Google reports: In a new episode of his podcast "Tick Talk," original Pebble founder Eric Migicovsky discusses the progress being made on the revival. This time around, the main topic is Pebble Time 2 and its "final design," which sees a considerable redesign compared to what was shown off earlier this year. The new look has some added curves, color accents, knurled buttons, and a stunning overall look.

It'll be available in black and silver colors, as opposed to the black and white previously shown off. In between the metal portions of the build, a polycarbonate layer will allow the radios to work properly, while also adding a blue or red accent to the design. Apparently, there are four total color options on the table, but they're not final just yet. Anyone who has placed a pre-order will get the choice of what color they want.

The new Pebble Time 2 will be made from stainless steel, in particular the same steel material that the original Pebble Steel was built from. It also has transitioned to a flat glass panel versus the curved finish that was used on prior Pebble watches, lessening reflections. The backlight on this model is also more advanced, with an RGB LED that allows the user to control the backlight color so it's not always "blue-ish." Migicovsky says that this will allow the color temperature to change through the day.
The Pebble Time 2 is available to pre-order for $225.

Jellyfish Swarm Forces French Nuclear Plant To Shut (bbc.com) 39

AmiMoJo shares a report from the BBC: A French nuclear plant temporarily shut down on Monday due to a "massive and unpredictable presence of jellyfish" in its filters, its operator said. The swarm clogged up the cooling system and caused four units at the Gravelines nuclear power plant to automatically switch off, energy group EDF said. The plant is cooled from a canal connected to the North Sea -- where several species of jellyfish are native and can be seen around the coast when the waters are warm. According to nuclear engineer Ronan Tanguy, the marine animals managed to slip through systems designed to keep them out because of their "gelatinous" bodies.

"They were able to evade the first set of filters then get caught in the secondary drum system," he told the BBC. Mr Tanguy, who works at the WNA, said this will have created a blockage which reduced the amount of water being drawn in, prompting the units to shut down automatically as a precaution. He stressed that the incident was a "non-nuclear event" and more a "nuisance" for the on-site team to clean up. For local people, there would be no impact on their safety or how much energy they could access: "They wouldn't perceive it as any different to any other shut-down of the system for maintenance."

Nvidia and AMD To Pay 15% of China Chip Sale Revenues To US Government (apnews.com) 61

In an unusual arrangement to secure export licenses, Nvidia and AMD have agreed to give the U.S. government 15% of revenue from certain chip sales to China. The Associated Press reports: The Trump administration halted the sale of advanced computer chips to China in April over national security concerns, but Nvidia and AMD revealed in July that Washington would allow them to resume sales of the H20 and MI308 chips, which are used in artificial intelligence development. President Trump confirmed the terms of the unusual arrangement in a Monday press conference while noting that he originally wanted 20% of the sales revenue when Nvidia asked to sell the "obsolete" H20 chip to China. The president credited Nvidia CEO Jensen Huang for negotiating him down to 15%. "So we negotiated a little deal. So he's selling a essentially old chip," Trump said.

Nvidia did not comment about the specific details of the agreement or its quid pro quo nature, but said they would adhere to the export rules laid out by the administration. "We follow rules the U.S. government sets for our participation in worldwide markets. While we haven't shipped H20 to China for months, we hope export control rules will let America compete in China and worldwide," Nvidia wrote in a statement to the AP. "America cannot repeat 5G and lose telecommunication leadership. America's AI tech stack can be the world's standard if we race."

Ford Announces Investment To Bring Affordable EVs To Market (freep.com) 130

An anonymous reader quotes a report from the Detroit Free Press: Ford is announcing the creation of a new electric vehicle production system and a new EV platform that will allow the automaker to more efficiently bring several lower-cost EVs to market, the first of which will be a midsize, four-door electric pickup that seats five, to launch in 2027. That pickup, which is expected to start around $30,000, will be assembled at Ford's Louisville Assembly Plant for U.S. and export markets. The Dearborn-based automaker said it will invest $2 billion to retool the Louisville plant starting later this year. [...] Ford's investment in Louisville Assembly is in addition to Ford's previously announced $3 billion commitment for BlueOval Battery Park in Marshall, Michigan, where Ford will make the prismatic LFP batteries, starting next year, for the midsize electric pickup. Together, the nearly $5 billion investments mean Ford expects to create or secure nearly 4,000 direct jobs while strengthening the domestic supply chain with dozens of new U.S.-based suppliers.

Ford executives and Kentucky officials also introduced on Monday, Aug. 11, the new Ford Universal EV Production System, which they said will simplify production and ease operations for workers. Ford leaders also announced the creation of the Ford Universal Electric Vehicle Platform, which will enable the development of "a family of affordable electric vehicles produced at scale." The vehicles will be software-defined with over-the-air updates to keep improving the vehicles over time. "We took a radical approach to solve a very hard challenge: Create affordable vehicles that are breakthrough in every way that matters design, technology, performance, space and cost of ownership and do it with American workers," Ford CEO Jim Farley said in a statement. "Nobody wants to see another good college try by a Detroit automaker to make an affordable vehicle that ends up with idled plants, layoffs and uncertainty."

Farley has teased this announcement since Ford's second-quarter earnings when he said Ford would have a "Model-T moment" on Aug. 11. He's referring to the classic vehicle that helped turn Ford into a mass market automaker and perfect the assembly line process. At that time, Farley said it was critical that Ford unveil an EV strategy that would position it to make money selling the electric cars and effectively compete against the Chinese, who are known for making high-quality, desirable and affordable EVs. "So, this has to be a good business," Farley said of Ford's investments in the new process and platform. "From Day 1, we knew there was no incremental path to success. We empowered a tiny skunkworks team three time zones away from Detroit. We reinvented the line. And we are on a path to be the first automaker to make prismatic LFP batteries in the U.S. We will not rely on imports."
Ford says its new Universal Electric Vehicle Platform "reduces parts by 20% versus a typical vehicle, with 25% fewer fasteners, 40% fewer workstations dock-to-dock in the plant and 15% faster assembly time." The new EV pickup built using this platform is targeting a "starting MSRP at about $30,000, roughly the same as the Model T when adjusted for inflation," adds Farley.

He shared additional details in an interview with Wired, such as how the automaker hired Tesla veterans Doug Field (who also helped lead Apple's now-defunct EV project) and Alan Clarke. "Turns out, Doug and Alan and the team built a propulsion system that was like Apollo 13, managed down to the watt so that our battery could be so much smaller than BYD's," said Farley.

The Engineering Marvel That China Hopes Will Help Wean It Off Foreign Energy (wsj.com) 58

China has begun construction of a $167 billion hydropower facility on Tibet's Yarlung Tsangpo River that would generate triple the output of the Three Gorges Dam. The project employs a run-of-the-river design, drilling deep tunnels through mountains to bypass the Yarlung Tsangpo Grand Canyon, where the river drops nearly two vertical miles over 300 miles. Water diverted through the tunnels will drive turbines at both ends without creating a large reservoir. The river currently produces just 2% of its hydropower potential. A $7 billion transmission network will deliver electricity to Guangdong province, Hong Kong, and Macau. China imported nearly a quarter of its energy supply in 2023.

As Electric Bills Rise, Evidence Mounts That U.S. Data Centers Share Blame (apnews.com) 88

"Amid rising electric bills, states are under pressure to insulate regular household and business ratepayers from the costs of feeding Big Tech's energy-hungry data centers..." reports the Associated Press.

"Some critics question whether states have the spine to take a hard line against tech behemoths like Microsoft, Google, Amazon and Meta." [T]he Data Center Coalition, which represents Big Tech firms and data center developers, has said its members are committed to paying their fair share. But growing evidence suggests that the electricity bills of some Americans are rising to subsidize the massive energy needs of Big Tech as the U.S. competes in a race against China for artificial intelligence superiority. Data and analytics firm Wood Mackenzie published a report in recent weeks that suggested 20 proposed or effective specialized rates for data centers in 16 states it studied aren't nearly enough to cover the cost of a new natural gas power plant. In other words, unless utilities negotiate higher specialized rates, other ratepayer classes — residential, commercial and industrial — are likely paying for data center power needs. Meanwhile, Monitoring Analytics, the independent market watchdog for the mid-Atlantic grid, produced research in June showing that 70% — or $9.3 billion — of last year's increased electricity cost was the result of data center demand.

Last year, five governors led by Pennsylvania's Josh Shapiro began pushing back against power prices set by the mid-Atlantic grid operator, PJM Interconnection, after that amount spiked nearly sevenfold. They warned of customers "paying billions more than is necessary." PJM has yet to propose ways to guarantee that data centers pay their freight, but Monitoring Analytics is floating the idea that data centers should be required to procure their own power. In a filing last month, it said that would avoid a "massive wealth transfer" from average people to tech companies.

At least a dozen states are eyeing ways to make data centers pay higher local transmission costs. In Oregon, a data center hot spot, lawmakers passed legislation in June ordering state utility regulators to develop new — presumably higher — power rates for data centers. The Oregon Citizens' Utility Board [a consumer advocacy group] says there is clear evidence that costs to serve data centers are being spread across all customers — at a time when some electric bills there are up 50% over the past four years and utilities are disconnecting more people than ever.

"Some data centers could require more electricity than cities the size of Pittsburgh, Cleveland or New Orleans," the article points out...

Chevy Silverado EV Drives 1,059.2 Miles on a Single Charge, Surpassing World Record (theverge.com) 102

"General Motors claimed a new world record for EV driving on a single charge," reports the Verge, "after a Chevy Silverado EV traveled 1,059.2 miles without recharging its battery." The potentially record-breaking run took place over seven days on public roads near GM's Milford Proving Ground and Detroit's Belle Isle "using smart driving techniques" that included limiting the speed to 20-25 mph. The truck was a 2026 Chevy Silverado EV Work Truck with an EPA-estimated range of 493 miles. But by making a number of adjustments, GM's engineers were able to far surpass the vehicle's estimated range...

First of all, the test was conducted in the summer for "optimum ambient temperature for battery efficiency," GM says. They also lowered the windshield wiper blades to reduce drag, inflated the tires to the highest acceptable pressure for lower rolling resistance, removed the spare tire to lighten the load, and optimized the wheel alignment. A tonneau cover was added to the truck bed for smoother airflow, and climate control was turned off for the duration of the test.

GM isn't seeking the Guinness World Records, the article adds, with a GM spokesperson calling it "a passion project led and executed by GM engineers." (The test "started out as casual conversation among a group of GM engineers in late 2024," GM says, but "quickly turned into a challenge: How far could the Work Truck go if we optimized absolutely everything?")

After the test, reports Motor Trend, "The dead truck was hauled back to Milford, its battery was topped up, and the energy used to power a Stratasys F370 3D printer, which spent 6.5 hours printing an ABS plastic trophy to commemorate the auspicious event."

California Successfully Tests 'Virtual Power Plant', Drawing Power From Batteries in 100,000 Homes (yahoo.com) 104

"California's biggest electric utilities pulled off a record-breaking test..." reports Semafor, "during the 7pm-9pm window that is typically its time of peak demand as people come home from work." Pacific Gas & Electric and other top California power companies switched on residential batteries in more than 100,000 homes and drew power from them into the broader statewide grid. The purpose of the test — the largest ever in the state, which has by far the most home battery capacity in the U.S. — was to see just how much power is really there for the utility to tap, and to ensure it could be switched on, effectively running the grid in reverse, without causing a crash.

The result, which the research firm Brattle published this week, was 535 megawatts, equal to adding a big hydro dam or a half-sized nuclear reactor at a fraction of the cost. "Four years ago this capacity didn't even exist," Kendrick Li, PG&E's director of clean energy programs, told Semafor. "Now it's a really attractive option for us. It would be silly not to harness what our customers have installed...." Last week's test proved that in times of peak demand, PG&E can lean on its customers' batteries rather than turn on a gas-fired peaker plant or risk a blackout, Li said.

Virtual power plants (VPPs) also facilitate the addition of more solar energy on the grid: At the moment, California has so much solar generation at peak hours that it can push the wholesale power price close to or even below zero, a headache for grid managers and a disincentive for renewable project developers. The careful manipulation of networked residential batteries smooths out the timing disparity between peak sunshine at midday and peak demand in the evening, allowing the excess to be soaked up and redeployed when it's actually needed, and making power cheaper for everyone. The expanded use of VPPs shouldn't be noticeable to battery owners, Li said, except for the money back on their power bill; nothing about the process prevents them from running their AC or dishwasher while their battery is being tapped. The network can also run in reverse, with the utility taking excess power from the grid at times of low demand and sending it into home batteries for storage.

California could easily reach over a gigawatt of VPP capacity within five years, Li said. Nationwide, a Department of Energy study during the Biden administration forecast that VPP capacity could reach up to 160 gigawatts by 2030, essentially negating the need for dozens of new fossil fuel power plants, with no emissions and at a far lower cost. In 2024, utilities in 34 states moved to initiate or expand VPP networks, according to the advocacy group VP3.

Even with a reduction in federal credits, virtual power plants "offer a way for residential solar-plus-storage systems to remain economically attractive for homeowners — who get paid for the withdrawn power," the article points out — and "a way to make better use of clean energy resources that have already been built."

Sunrun's distributed battery fleet "delivered more than two-thirds of the energy," notes Electrek, "In total, the event pumped an average of 535 megawatts (MW) onto the grid — enough to power over half of San Francisco... This isn't a one-off. Sunrun's fleet already helped drop peak demand earlier this summer, delivering 325 MW during a similar event on June 24.

"The company compensates customers up to $150 per battery per season for participating."

ThinkPad Designer David Hill Spills Secrets, Designs That Never Made It (theregister.com) 39

alternative_right shares an interview from The Register with David W. Hill, who served as lead designer for ThinkPad from 1995 to 2017. Here are some excerpts from the wide-ranging interview: Hill revealed that he tried several times to introduce additional laptops that had the famous "butterfly keyboard" found on the ThinkPad 701C. [...] Hill told The Register that he had wanted to make more ThinkPads with butterfly keyboards and had tried at least three times to make it happen -- in one case there was a prototype where only half of the keyboard moved -- but was never able to get there. Eventually, screens became big enough that there was no need to have a keyboard that expanded. However, Hill said, he thought about putting a butterfly keyboard on a netbook when they were a viable product category in the late aughts. [...]

One of the features Hill is most proud of developing is the ThinkLight, an overhead light located above the screen that lit up the entire keyboard and deck. Though the advent of keyboard backlights has made the ThinkLight redundant -- Lenovo discontinued it in 2013 -- it offers capabilities that backlights do not. If you want to place a paper on top of your keyboard, the LED will light it up, allowing you to see more than just your key legends. ... When designing the 25th anniversary ThinkPad, which came out in 2017, Hill brought back the ThinkLight, but he actually wanted to have -- for the first time -- two LEDs instead of one. The dual lights would have eliminated shadows and provided even better illumination, but unfortunately, this effort proved too costly to make it into the final product. [...]

When I asked Hill about products he wanted to come out with but never got to, he talked about an idea for portable workstations that would fold up like a laptop but have a separate keyboard and screen like a desktop when you put them on your desk. He collaborated with butterfly keyboard creator John Karidis on this concept, but couldn't make it ready for market. "We did a lot of experimentation with laptops that sort of unfolded to be more like a desktop: things where the display elevated or the keyboard would remove so you could use them like a workstation, rather than just being a clamshell with a hinge, you open and close," Hill recalled. "We did a lot of experimentation with that and got close a few times, but never could completely sell it. I always thought it was an opportunity to create a new category."
