Color me less than impressed, but wasn't the original mockup of the Optimus keyboard a full 108 key keyboard? At $159 for three keys, I can see why the larger board wasn't produced.
that's rediculous ($1200) The primary use i can see for the 3 key version is hotkeys for your crucial apps- music, navigation, video? w/o having to reach for the screen or a more full featured keyboard... and of course eye candy & boast factor.
