Wow, typed a book there... Didn't read all of it though because I'm sick and tired, so my attention span is about 30 seconds right now, but IMO, yes, the PSP Slim is worth it, unless you're mostly going to use it music and videos with a hint of gaming, than I'd get a 80 GB Zune because they've got games coming out any minute now, if they haven't got them out already and it's main purpose it to play music and videos.
Basically...
If you're getting it mainly for music and video with a bit of gaming, I'd get the Zune.
