My son has had an IPOD nano for about 1 1/2 years. A couple of months ago, the middle button quit working, but it would still play. Now it seems to be frozen. We have tried to dock it or charge it at the computer, but it is still frozen. I know it is not terribly expensive to replace but I hate the thought of having to. I would like to think that even a $100 or so IPOD that was kept in a rubber case (like a Michelin tire) would have lasted longer. Has this happened to anyone else? If so, were you able to repair it?
