An anonymous reader writes: At IFA in Berlin, Lenovo announced the Yoga Book, a laptop that measures in at just 0.38-inches thick, making it the thinnest laptop currently available. In order for it to retain such a slim profile, the keyboard needed to be redesigned. The Yoga Book features what is called the Halo Keyboard, a touchscreen keyboard that is separated from the display and doubles as a drawing tablet. Gizmodo reports: "Officially it's called the Halo Keyboard, and if you've ever tried to quickly type on a tablet's software keyboard than you'll be familiar with the experience. Only it's a little nicer because the keyboard is separated from the display, so it doesn't suck up screen real estate, and it has a pleasantly rough texture. It's also got haptic feedback, which in the case of a touchscreen keyboard is sort of like sticking lipstick on the pig. A press of a button turns the keys off and turns the keyboard into a drawing tablet. From there, it behaves a lot like a Wacom tablet, directly reporting pen input into your chosen app. It even reads pen inputs through paper laid over the input panel." Some other specs of this 2-in-1 laptop/tablet include an Intel Atom processor, 64GB of onboard storage with support for a microSD card, 13 hours of battery life, 4G LTE, 802.11 AC Wi-Fi, front and rear cameras, and a 10.1-inch, 1080p display.
