I am going away this summer, cross country and need to buy an ipod. I really dont listen to much music, but i am going to be on a bus a lot so i need something. I was just going to get a shuffle because its nice and cheap, only 100 bucks, but i just realised how am i going to charge it? Doesnt it only charge through usb>? I wont be near a computer barely at all this summer, so i might need to go ipod mini.
