^Yes it's the newly-designed Nintendo DS.
Yes as the above guy said PSP (for now) is a waste of money because
there aren't any must-have games for it.
While for the DS (half-ed the price of PSP), you get to play
NDS/GBA games. And that's a lot of great and innovative
games.
If you think the current DS is kiddish, you can wait for the DS
lite which makes you look more mature and adult.
