Just returned from Best Buy with just my basic PSP unit, cause of income right now. And just so I have one. I was asking people what portable unit was best of all. Most have to say the GAMEBOY SP Why because people say its comact, has a closing cover, plays ALL games and the rechargable battery lasts. No one had a say in the PSP yet but the battery may have a drawback with the power it needs to run movie music or games.
