based on your OP, I'd definitely go for the PSP. It probably has more games that you would like and it has an excellent media player (and Remote Play!) and you can even use it as a cell phone if you have Skype. You can also get some really cool homebrew FW and apps if you want to.
Not trying to be a fanboy. Of course, it's hard when you own the best console eve... dang it
