Re: iPod 4th gen?
I'm on my 2nd 4th generation ipod. My first one was fine until all of a sudden I got this crazy error that no one can really explain, apple included. Luckily it was still in the warentee and apple was brilliant with it. Sent a box with foam and everything for me to mail out and 2 weeks later a new one. However, if it had not been in the warentee, I'd say I'd have been screwed.
Unfortunately all ipods tend to suffer from the same problems - they can sometimes unexplicably get screwed up, and are fragile. Otherwise, they're a great music player, and my new one has been fine so far. Just don't pay too much. E bay is a good place for those kinds of electronics, though.
