The Optimus keyboard is absolutely sick looking. I've been keeping an eye on it, and it looks like it's going to be some pretty serious $$$ when it's released.
Apparently you can even program the keys to randomly change the images that they display.
Having a set of programmable images for different games and software would be amazingly helpful. You could label hotkeys or action keys on the fly so you'd never need to look at those obnoxious shortcut lists or keypad layouts again...
on top of that, nobody born before 1975 would be able to figure out how to type on them... Sorry Lush!
