Well. I bought a PSP, iPod, and just recently upgraded my PC a bit (just got some more RAM and a new monitor). I like my PSP a lot, but I hardly ever play it. I'm actually thinking about selling it right now. Between my PC and iPod, I think I use my pod about 2x's as much as my computer. But hey, that's just me. I like music that much.
Anyway, it's really about what you think you want/need more.
