Loot Ninja picked up a Star Wars edition PSP Slim yesterday. They decided it was time for a new one, since their battery was dying off anyway. They really wanted some of the new features, and they're fans of Star Wars merchandise.
Aside from the really cool looks of the white PSP with the Darth Vader image on the back, there are huge number of great refinements to the PSP Slim. Everyone has heard the usual, that the unit is much lighter and thinner, which are both very true. The screen is also brighter and the unit loads faster with more included RAM. But there's a lot of other features that haven't been widely discussed that make it that much better.
