well there really different....psp is awesome for games, its like having a playstation2 that you can take anywhere, and you can put music, videos, and pictures on it. you dont need to buy anything else once you get it unless you want to upgrade your memory which i think is pointless because you really dont need to put hundreds of videos and shit on because you can just chnage them whenever you feel its needed. an ipod is all for the music, so it depends on what you want. psp has more, and is more interactive and personalized, you can also go on the internet if theres wireless near you....my vote is psp
