I tried one some time ago (under a different name IIRC) I'd already used a nostromo by then I didn't make the change. I found it too flat with an awkward layout, I have bigish hands with fairly long (artistic my mum says) fingers. So it wasn't really a size issue. But it might be I just prefer the n52 so far. Equally I can't use the keyboard for FPS/WoW because my hand cramps after a bit.
