I'd have to agree with the lobster people comment. Neither the GBA with it's poorly placed L and R buttons, or the SP, which though improved, is too freakin small have anything on the GBC or original GB. GBC gets fat right where your hands need it, while remaining small enough to fit in a pocket. I just carted mine around to play between holes on the golf course while we waited for the two groups in front of us, and it was perfect.
