What are the advantages of a PSP-3000 over a PSP-1000?

Its smaller, lighter, I beleive it uses less battery consumption, the screen is much better and brighter. But the game tray on the PSP-1000 is better

And yes, I would probably tease you if I saw you with a Hannah Montana PSP,  but thats because I can be an asshole at times
