Synaptics has been working on the ThinTouch keyboard for quite some time now, but going hands-on with it was a treat. The new keyboard, destined for laptops, is even thinner than that of the MacBook Air. Synaptics achieves this through a rather ingenuous mechanical move. Think of tapping a key on your keyboard, it moves straight down. That's the travel of your key. The ThinTouch travels diagonally, shaving the distance it must travel and resulting in a thinner keyboard.
