PsP has better graphics and can do more but is more expensive and memory cards cost money, The D.S has more games and a touch screen so it all depends on what you like i guess. (personally i like the psp better)
psp is for 13 and up. thats the only way you can have fun. that ds shi.t fuc.ki.n suck.s you cant have fun with a ds unless your semi retared or a 5 yaer old
No, I'm saying why I don't like PSP over DS - because it's not a real gaming console, it's what happens when you let non-gamers design a console: utter failure.
the psp is a better on design because the ds topscreen is very fragile. but the ds is better on ideas it has a touch screen built in memory gameboy slot and wifi. and the ds is alot cheaper.
