psp go has flash memory psp in general has good graphics not good interface. ds in general has horrible graphics good user interface dsi has flash, ds/ds lite is back compatible so psp 3000
hmmm well dsi has alot of cool wi-fi software but a you can do alot with a psp so...i say... then agin u can do half the same stuff with a dsi that u can with a psp...hmm i say Duel Screen interface! DSi!
Lifes like a game there are those who are good at it and those who need practice.
In my opinion i think dsi is better because psp/pspgo takes too long to get internet and its too difficult and the psp dont work with certain games. my brother was playing a yugioh game it blacked out on him . the psp was on and the screen is just black. and he never used it again. Sony Computer Entertainment America you should really do something about this issue. So Dual Screen interface rocks. Dsi dsi dsi
