To each his/her own, but that is the ugliest board I've seen in a while:
1) I'd never be able to hit that space bar...it sort of has the whole erase ease thing going with the backspace where the right thumb goes; however, it's backwards. I'd bet that most right-handed users would be used to using their right hand for the Space, and since the space bar is hit more than the backspace...can we say "major design flaw"?
2) It's nice not having a very prominent Caps Lock key, but since they put the Ctrl where the shift is located...I foresee problems there as well.
3) The Enter and Tab are just ridiculous.
Just look at the friggin thing, when there are many very nice Topre boards already out there with small form factors. And, why are some of the letter keys different sizes...how often do you actually need Z for it to be so dominant?
