PSP wins easily if you had both machines you would understand why...

I have both a PSP and a DS and although the DS is great fun and very inovative for a handheld the PSP offers a LOT more than just playing games...

i prefer sony psp because in my country you cant find a single device of nintendo ds but easily you can find a PSP and its easier to find its games.

well. the psp console is superior in many points of view, the little machine, if the owner know how take advantage of it, have a little pc, for example, i have both consoles, but the PSP is very practically to me in the college, i store my class work in , i can print , or i can browse information in the network, but the psp can be customised, the windows xp can be uploaded and used also, the office can be used and works can be created with the psp, the games are more realistic, like the ps2, not exactly but it seems like.

also the psp can be used in the tv, can be used to watch movies, internet, pictures,music and with out have to buy accesories to make run those features.
also the psp games has game server online to play with people around the world.

well, u must have both consoles to know well the diferences between, but one common thing here is, they can run games :P jajajaja

DS FOREVER YOU CAN USE THE STYLUS TO PLAY, NINTENDO IS SO CREATIVe!

It really doesn't matter since I have Castlevania games for both Handhelds, but Trace Memory and Hotel Dusk are ups for DS so I guess they're still matched
