The DSi has a camra and better screens, but the psp can play movies WITH A PERFECT PICTURE. I am currently borrowing my best friend's PSP and i luv it, but have never touched a DSi. Would I like DSi better?
I don't like PS anythings but get the PSP, the DSi sucks. No GBA slot, which some games require to play and many need for special features, so it's a rip off. If you get a DS, get a DS Lite.
God, the DSi is a ripoff. Don't get it. All that's changed from the DS lite is bigger screens, longer stylus, and a camera(crappy at that). Don't get the PSP, don't get the DSi, get the DS lite.
