The Lenovo Yoga Book represents incredible innovation in the Android convertible space. A tablet that turns into a laptop when necessary, with the multitasking chops to act as a fully-fledged desktop replacement, it sets the standard for Android slates.
It opens and folds around the stunning watchband hinge, but instead of revealing a traditional keyboard you're greeted by the touch-sensitive Halo Keyboard. No physical keys, just a big sheet of glass. With the tap of a button the light-up keys disappear and you get a full touch panel on which you can write and draw with the included stylus, or you can put a pad of paper over top of that and write with ink and see it transcribed onto the display.
