With both "terminals for charging" and a DC in connector, I wonder whether the PSP will come with a cradle charger or just a standard adapter in the box.
I'd guess it would be to return to the frontend GUI to access things on the mem stick, a local wifi network or other things, without taking out the game or movie. You know if could get annoying if you had to take out the UMD and reboot everytime you wanted to access the frontend.
Blue tooth? wasn't it wifi? *points to wireless LAN switch*
and it's got an IR thing too, though I have no idea why. I mean, why the hell would anyone use that IRDA thing? I've never seen someone use it, or a device that could, except for an old toshiba laptop... maybe PDAs can, but I'm not concerned with those, and why would you want to synch a PSP with a palm anyway?
having to use Magicgate Duo sticks is gonna be a pain though, if I had known that a few months in advance I would have bought that for my cybershot and killed 2 birds with one stone instead of geting a plain vanilla sandisk 128MB 'stick
