Nintendo DS or PSP?

[Multiply]

Technically, a PSP is wayyyyyyy better than a DS anyday..
However!:

omg, on my school camp there was 74 kids. 65 of them had their ds and we had a MASSIVE mario kart lan on the bus. it was soooo fun. the bus trip was 48 hours thats ALL we did

That's the why the DS is more fun.
