If Tuition didn't set me back $1100 last week, I'd have one now...
I do admit that the game selection is still weak but I would get the Mario 64 DS, Mario DS and Sonic DS out of the currently announced games.
Plus with GBA games still being released (DKC3 soon then I buy all three) and the wireless chat feature make it a good buy (I have very boring lectures and a few people already have it)
