mlord you can get ten hours with the old battery. Im definitely getting the black one and giving my brother my old one. Oh and the new memory stick gate looks really cool. P.S. everyone asking why they didn't put another analog stick on the redesigned model; they didn't want to screw everyone who doesnt want to buy the PSP slim. If they added a second analog stick then you would be forced to buy the new model if you wanted to play the games that required two analog sticks.
