I’m not sure there’s anything ergonomic about the Optimus Keyboard (though they promise a “split keyboard” in the future), but I had to mention it for the mere coolness factor.
Set for release in 2006, this keyboard will work easily with any language or layout (want to switch from QWERTY to DVORAK? No problem.). What makes this possible? Well, every key is a mini screen. You can program what that key represents and the screen will change to display its function. The manufacturer promises the keyboard will handle not only any language but also special functions for gamers. The cost? “It will cost less than a good mobile phone.”
You can also read the comments over at the forum where I first read about it: Optimus Keyboard Discussed at Webmaster World.
