psp is clean as fuck, best hand-held unit out. all u need is a 1 gig or high memory stick and ur set. u cant d/l emulaters (programs that convert old rpg's to psp format) and u play on ur psp! like old school mario and street fighter. U can also throw movies and music on there, connect to the internet when ur in a free wi-fi area. i stay with my psp all day or when i was at school. Its clean now cuz u can use ur psp to connect to the ps3 if u have on. U can hook it up to where u can watch all ur movies on ur ps3, on ur psp, without using the psp's memory. say ur watchin a movie thats saved on ur ps3's HDD and u have a psp, then u have to take a shit, just connect ur ps3 to ur psp (wireless) and take it with u and watch it while ur takin a shit
