It's iTunes that has the problems and runs slow, not the computer itself. MS had a press release a while back explaining why it was....basically Apple refused to code it a certain way despite MS's insistence otherwise hence the instability and pathetic performance. Maybe someone can clarify that. iTunes is a horrific program on PCs and the only reason I use it is because Apple forces you to use it for the iPhone. Imagine if MS did something like that, they'd be in court quicker than you can blink. It's amazing what Apple gets away with.seriously if you notice your computer going slow from itunes... it has issues.
