I just received my new ipod in the mail today but my new imac won't be here for a couple days. Will I hurt the ipod by charging and using it on my G4 with old usb ports so I can play with it until my new computer gets here? I know it would take longer to charge and transfer data, but I can't think of any reason it would hurt it. But apple batteries are a funny thing. Just thought I'd ask before doing. Thanks, Dan.
