Thinkgeek got their hands on a final production sample of the Optimus Mini Three keyboard; the keyboard that only has three keys. Despite that, each key has an OLED display on it that you can use to show whatever you want. Examples are weather, how much free memory you have, how much your current CPU usage is, or a 3FPS webcam stream. It’s only Windows compatible for now, but Mac and Linux support is under development.
Ships mid-september for $159.
Optimus Mini Three Keyboard [Think Geek]
It looks just as useless as I had imagined. I understand though, that this is more a proof-of-concept for the full size keyboard than anything else.
I might actually consider buying one of these if it looked a bit sleeker and was made ready to mount to the bottom of an LCD. The last thing I need right now is another gadget for my physical desktop.
