I want to get my brother an iPod for Xmas; however, he has a PC. I know there are PC iPods, but what do I have to do to get one? Do I just go up to the guy in the Apple store and say "Yeah, I need a PC iPod?" or will any iPod do; is there a difference between the two? Can anyone tell me if he will need Xplay or anyhting like that? Thanks!
