OLPC Halves Power Consumption For XO 1.75 160

Posted by timothy from the conservative-versioning dept.
angry tapir writes "One Laptop Per Child (OLPC) has reduced the price of the next version of its notebook to US$165 and power consumption has been slashed by half compared to the previous version. The XO-1.75, with its 8.9-inch touchscreen, will start shipping in the second quarter of this year."

  • I'm convinced, after looking at the proposed specs and the mock-ups for the that the $165 price-point is a pie-in-the-sky fantasy.

    But... If it does miraculously appear for under $200 and can run Android or some other Linux variant, I'll buy 3 or 4...

        The actual cost of non-premium hardware is very, very little. For instance the screen in most netbooks only costs about $10-$15, probably less in bulk. The only reason Ipads cost so much is they use under-clocked top of the line CPU's, IPS displays with lots of SSD space and a capacitive touchscreen in an expensive aluminum case. Now if you stick to a cheaper non-IPS display and use a resistive touchscreen and reduce the storage capacity and put it into a cheap plastic case... and you end up with a cheap

      No that would have been pointless at the time. If it isn't apparent by now their whole plan was to wave the penguin flag until Microsoft came through with a cheap enough deal you haven't been paying attention. ARM would have made that plan impossible. Besides, they had AMD in as a partner at the beginning... until they used them as a lever to force Intel to give em a sweet deal. Problem was once Intel got AMD out they stopped giving em free stuff because by then it was clear there was zero chance Negroponte was actually going to be able to deliver on any of his promises.

    The main problem with the OLPC, the one thing that made the project open to subversion by companies like Intel and Microsoft, is its centralized model of development. You get the laptops or tablets from one source, say, the central government of the country that buys into the idea or some buy-one/donate-the-other scheme. I understand that it's supposed to be more of an educational than a computing project. But this set-up generates dependency. What happens when the machines are damaged? More importantly, what happens to the next batch of children without laptops? Since the machines are manufactured in the usual Asian places (hint: two countries claiming the same name), this will likely result in a foreign exchange outflow from a country that can least afford it, as certain essential non-technological items (e.g. food and basic medicine) may need to take priority.

    What the OLPC should have set out to develop is a RepRap [reprap.org]-like infrastructure that will allow the adults (or even older children) of the community that takes part in the project to manufacture the laptops by themselves from cheap, readily available components. If this isn't 100% possible, then give them at least enough transfer of technology to allow them to build the least technological parts, like the case or the keyboard. Think of a laptop case made out of recycled plastic or hard laminated cardboard. Then again, how far off is the day when we can run a desktop OS on an Arduino [arduino.cc] board?

    I never thought I'd be a beneficiary from the OLPC project. I'd never be able to use an OLPC for anything I do. But I love how the project has put a bent in the technical landscape of portable devices industry. It was a failure as an education project perhaps, but it succeeded in more than one way as a laptop research project.

    When OLPC came out in 2007, the laptops were on a lap-melting, back-breaking rush towards bigger & faster. Nearly everything came in with a Core2 or a Core2 Duo, with lots of RAM (yeah, guess what you can't save power on, RAM needs a strobe whether it has data or not). The fact that OLPC came out in 2007, sort of forced the geeks to look at weight as a valid concern for a consumer device. Not to mention questions about why a 1995 top-end laptop ran for 4 hours on batteries, when a 2005 one won't do the same at the same weight.

    Less than a year after OLPC came the rush of netbooks. Finally machines that people can afford to buy (like here in India) and carry around without being tied to a wall plug. Scroll paste a few years, it is not only consumers, using them. I see Rasmus [lerdorf.com] post PHP benchmarks off his netbook, I see entire teams (like Inkscape) suddenly sit up and re-work their UI workflows/dialog-space for it. I see the Notion Ink use OLPC Pixel Qi tech in the new tablet.

    Socially speaking, the project has been a great failure. But technologically, it has left a huge impact on portable devices everywhere. As for the former, the project probably forgot that "Charity begins at Home". Refusing to sell full-price to americans wanting them shows a complete lack of understanding of how economies of scale & price segmentation would've worked out. I'm not going to mourn the failure of Negroponte, but I'll just give the technical folks at OLPC a big thumbs-up.

      • Bah, I doubt OLPC had anything to do with it at all. The thing that launched the whole market in 2008 was because Intel suddenly had a dedicated low-power design in the Atom not just LV/ULV versions that were custom versions/bins of existing designs with large dies. The extremely small die size compared to all the other processors gave Intel a reason to flood the market with cheap computers and still make a very, very solid margin.

        Intel pushed Celeron-M / i915 platform for "Classmate" as a competitor to OLPC. Asus partnered with Intel for the original EeePC: http://www.pcmag.com/article2/0,2817,2141742,00.asp [pcmag.com] What does it contain? Celeron-M, not Atom. In fact the Celeron-M can't even make use of the power saving SpeedStep on identical Pentium-Ms. It seemed clear these Celeron-M machines (either in Classmate, or in EeePC) was a stop-gap until Atom could be released.

        Atom was originally designed for other embedded applications, and not

  • With the previous OLPC laptops, a lot of effort (IIRC) went into finding hardware chips from manufacturers willing to provide open drivers.

    Will the same thing apply to this new OLPC? Or are they abandoning the idea of openness?

    I've tracked the OLPC project and have worked in educational technology for years, and arguments over processors and power consumption are bullshit. The same goes for the philosophies of education behind educational technology. At the moment, the biggest issue is teacher training. Simply put, most teachers don't know how to use computers in the context of classroom teaching. That's even true when it comes down to the basics. Sticking an ARM processor into the case isn't going to solve that. Getting the computer to run on 2 Watts isn't going to solve that. Praying that the child is smarter than the teacher when it comes down to adopting new technologies for learning isn't going to solve that. Indeed, this emphasis upon technology over learning and these idle hopes that children are better at using technology for learning have left educational technology in the same cesspool that it was in 30 years ago: teachers, the people who are responsible for guiding children through the process of learning, are almost as ignorant about how to use it today as they were way back then.

    (For what it's worth, I think that there is some value in the 'student is smarter than the teacher' mentality when it comes down to educational technology. Yet that only works for a subset of children, since it involves a lot of self-motivation.)

    • To their benefit, OLPC has talked about this as part of their mission. They're not ignoring it, but one thing I'm finding is that OLPC is playing a Long Game (possibly because sales of the devices themselves hasn't been lucrative enough to finance the later phases of the rollout as quickly as they'd hoped).

      Teacher training is an issue in the developed world as well. I work with assistive tech for kids with disabilities, and I always hold that if I walk into a classroom and the teacher says "Oh, thank God yo

  • I have a G1G1 OLPC 1.0 that we bought in a fit of enthusiasm back when they first came out. These days, it sits untouched.

    The greatest highlight on the device was the great screen. I certainly hope Pixel Qi finally starts shipping in volume at a reasonable price. The eReader mode looks great, and I'm sure they've improved in the intervening time. The tough, splashproof hardware was nice too.

      This is the expected result when you write your GUI in Python. (same as Ruby or Javascript)

  • It is unconscionable to construct a summary specifically about power consumption without actually stating what the effing power consumption is. We have units for these things, people. Why always use the relative ones?
