Yeah, the DS has some great endurance. PSP not as much, though that may well be because mine's used and idk how the previous people(s) used it.

But yeah I do like that the PSP doesn't blink XD

ah, it'd be nice to hear more 3DS details, though I'll probably not be able to get one until the time they come out with 3DS lite or whatever :p *still has the ol' block ds*
