OHMYGOSH. The Optimus Keyboard, with an OLED display under each key, has a launch date. Supposedly 1st February. The price? Only your first-born child.
You can customise the keyboard so that each key displays exactly what it does. So if you play games, you can make the keyboard display game functions, for example, they have mapped the Quake controls to the keyboard. And it looks really cool. They are vague about it, saying that it would cost about the same as a “good mobile phone” which, I would guess is over $200, at least.
I have to settle for my Saitek Eclipse keyboard, which is very nice, but not nearly as cool as the Optimus. Priced quite a bit less.
