Am I the only one who wants these only to write new software for them? Voice-controlled is nice and flashy, but I doubt would suffice for any "real" work. I, personally, like the idea of gloves and a windowed interface on HUDs, the kind of gloves that let you tap your fingers to do certain actions, along with some identifier for tracking so you could "click" on the screen. I was also thinking about looking into a 3d windowed interface, relative to your glasses, but detachable into the enviroment so you could put you virtual keyboard on your desk and go get coffee; when you came back, it'd still be there.
