The Optimus Maximus from Art Lebedev Studio. This is what a $1500 keyboard looks like. Why so expensive? Each key contains a tiny customizable LCD screen. Want to be able to label your keys according to what they do in the application (or game) you're using? Want to finally have an "Any" key? Want to just put a picture of a boob on your "O" key? Well, now you can. That is, if you want to pay for a keyboard that's probably worth more than my car.
I've been watching the progress on this keyboard for a long time. I hadn't seen the price tag until now! That's insanely expensive!
It does look cool as Hell though! My hopes of ever owning one are dead... ;-)
