Wow! For $1500 that thing better be spill proof. Keyboards are not like computer screens, keyboards wear out, fill up with dust, keys break, things get spilt on them, and so on. A keyboard like this seems like it would be even more delicate. What if a key burns out? Now you have a key without a label. It is really cool, but it isn't all that practical for regular use. How often do you actually look at your keyboard? It would be very useful for foreign characters though, but too expensive to be practical. If the technology takes off and gets cheaper as time goes on, then these could be excellent. But I feel anything over $100 bucks is WAY too much for a keyboard.
