Now that's way too ergonomic for my taste. It also requires huge space that I don't have right now.
I am happy with a split keyboard in two pieces and no numpad.
It's not nearly as big as the pictures make it seem, although there's plenty of volume to them.
It looks big from the pictures, but it's not. As I recall, MS' Natural 4000 takes up more space. On my desk, it fits into the space formerly occupied by a Goldtouch V2.
