My wife knows me well, and when she saw the leap motion, she decided to order me one as part of the pre-order group. It arrived about a week ago, and I have used it a few times since. I don’t really spend a lot of time in front of my own computers these days, having a child around makes that a luxury. So far, though, my experiences with the Leap Motion controller have been positive. I have managed to calibrate it to a setting I am comfortable with, and have used it to draw things and play Cut the Rope. I am looking forward to a gesture recognition applet coming to the Air Space store so I can use simple gestures to compliment my mouse and keyboard use. I think that will be the killer app for the Leap Motion, more than being a mouse replacement.
