Do you already have a game system? How well does he do with that? I have not used the ds but I've seen friends with them. How are his fine motor skills? It looked like something a clumsy kid would break or get frustrated with.

He does pretty well with his Gameboy advance. When Jr. lets him, he does okay with the Nintendo 64 (but that's a bit outdated).
