To be honest? I'm not really sure anymore. I'm thinking of less and less stuff that I'd do with it that I can't already do with stuff I already have. Really, the only thing I can think of is playing emulated games, and who knows how long that'll last me for. Sure, I can play music, but I already have an MP3 player. Sure, I could play homebrew, but who knows how many of those come out that will interest me. I have PSP and Wii homebrew-capable, but no real homebrew on either of them, (except for scattered emulators, PSPComic and iRShell on my PSP--and I don't even use PSPComic anymore). Maybe I could watch some videos or something, but I hear the Pandora will be pretty taxed playing even SD XviD (IIRC, maybe I was thinking of SD H.264--either way, a lot of my videos are higher res than that, so I'd have to either convert them or just watch them with downsampling).
So I'm conflicted. It looked really cool a year and a half ago. But now, my interest is waning :/ I'd be happy if you guys could give me more reasons to want it, though.
