While I wholeheartedly agree with the curved concept, the layout is completely wrong.
He keeps a QWERTY layout, but has right-hand keys on the left side. The numerical keyboard is also unortodox.
The
Enter key is at the position of
Backspace, with the
Backspace key above it. The
Shift key is put at the
OS key's position, etc ...
I attached the same pic, but in higher resolution so that you can see for yourself.
My impression is that this guy is a
designer, not a
usability engineer. Those two should never be mixed up, even if the
designer says that he can design user interfaces. (Yep, I hold a grudge from having worked with one at a project ..

)
