[quote name='imascrub']i don't suppose there are any travel/carrying cases for the slim yet?[/quote]
Not that I've seen yet.
The original case that I had when I got my original PSP (the one that came with the slip case, 32mb mem stick, Spider-Man 2, headphones, and all that jazz) worked, but compared to the phat PSP, it's loose. Of course, the phat PSP was so snug I thought it was gonna bust the seams of it, but this one's sliding around, which just goes to show how much slimmer it really is.
I decided to buy one of those $10 small zip cases from GameStop (got it for $3 used), and it fits perfectly even with the games in there too.
