the problem of the sexy slim ipod nano may be with its polycarbonate coating.it is a plastic coating but seems more softer than other i pods'.some users of ipod nano says that they put their ipods in neat pockets but scratched seriously.the great trouble of the " impossibly small" ipod nano is that only a few scratches are enough to make the colour screen useless.the damaged screen will make you bored when you try to view album or photos stored in the machine.the plastic coating of the screen and front is very much sensitive..even the i pod nano becomes scratched within minutes..
If you are going to get a new ipod nano,try to get a white one because the blemishes are less likely to be noticed.and also pick up a case from an accessories house such as belkin or speck..
