Virtual Laser Keyboard: One Step Closer to Rocket Cars?

When it comes to keyboards, I really prefer the old thick, heavy, clunky-chunky keyboards. I like knowing I've actually struck a key, so the more biofeedback I get, the better. Having said that, I thought this was pretty amazing. Not so much that I'd want one, but it changes a paradigm for me about what else might be possible. What could this allow us to do, in a library setting, that wasn't possible before?

Avatar and Terra Nova in particular are Sci-Fi titles that have used virtual keyboards, and I always thought 'Nah, that'll never happen'. Well, I guess I should make room in my garage for a rocket car.

This model is put out by Celluon http://celluon.com/ but I 'borrowed' the image from here (it was better). http://www.thinkgeek.com/gadgets/cellphone/e722/?itm=celluon&rkgid=328562980&cpg=oggdgt1&source=google_gadgets&creative=9124005525&adpos=1t1&gclid=CPyXxI7646wCFYTsKgodkUsRRQ
