I've got mine as well
Though I'm at work just now so no pics for the moment!
Really isn't that much bigger than a DS Lite, and the weight is pretty decent.
Kept hitting the space as if it's under "b" though, heh.. and the placement of the shift will take a bit of getting used to, but it's all good
The nubs are interesting as well, the right one is looser than the left on mine, but doesn't seem to affect anything and I'm sure the left one will loosen up after some use anyway!
All in all, very pleased so far.. just waiting for my lunch so I can have a proper fiddle
