PSP or 30Gig iPod Video?

Both are about 300 bucks.  Both do most of the same things but iPod has 30Gigs and the PSP plays games.  I need your help.

If you get an iPod, make sure you know how to take care of it, because you have no idea just how many people I see come into my work saying "OH GOD MY IPOD DOESNT WORK I NEED IT TO LISTEN TO WHILE I JOG"

Obviously you shouldn't try moving around a lot with a spinning hard drive
