Nintendo DS the games are funner and theres more variety.

PSP.
Nice screen.
Nice sound.
When you play on it, it's really easy to get into the game.

the ds has the best rpgs psp has really good action games

i'm thinking of buying a PSP next month. i hate the thing that @ some games you DO have to use the goddamn pen in DS. it should be option i don't think the gameplay gets any enhancement by using that device

I've got to hand it to the PSP.
Of course, this is coming from a modders perspective.
The homebrew capabilities on the PSP far outnumber the DS's. In my opinion anyways. The PSP has a nicer screen, better sound.
The ability for me to store as much "stuff" on a 16GB memory card on the PSP as you can really gets me too.

Wait for the PSP Go

yep i want it pspgo comes out october first i think it was well first week of october

What are the new features for that? I never had a PSP myself and now seems like a nice time to get a phat one since the price will be dropping.
