I'm excited about the Leap because I rapidly transition my hands from the keyboard to the mouse and back again. That takes a lot of time and the mouse is hard on my wrists. I would much rather "mouse in the air" even if I lost some precision. My productivity would soar. Furthermore, my pinkies and thumbs take a beating pressing the command, control, and shift keys. I would much rather wave my thumb or pinky in a particular direction to get those modifiers. This may not be possible with the current Leap, but will no doubt be possible soon.
