Hi My Nano just died! It worked fine for 3 weeks and then as I was trying to recharge it, the logo onscreen vanished and it is completely unresponsive. I use a a pretty fast PC laptop with USB2 Is anyone else having problems? I guy I worked with had the exact same problem, and he had to buy a separate charger. Why should us PC user have to buy something extra when it is the IPOD's fault?????
