When the original Lenovo Yoga came out, everyone seemed to have the same complaint: when you flipped the screen over into tablet mode, you had to rest your hands against the keyboard on the other side. It didn’t matter that the keyboard automatically disabled; it felt awkward to press your fingers into flappy keys instead of a smooth surface. Well, Lenovo seems to have taken that criticism to heart: the company just announced the ThinkPad Yoga, a 12-inch, business-friendly model with a keyboard that flattens as you flip the screen back into tablet mode. How does this so-called Lift and Lock system work? Here’s the short version: as you flip the display over, a mechanical setup causes the platform between the keys to rise so that it’s level with the buttons. Meanwhile, the keys get clamped in place so you can’t press them. Finally, folding the screen over causes a set of feet to pop out so that there’s some buffer space around the keys when you place the “tablet” face-up on a flat surface.
