If a brand new iPod classic is connected to a PC, and then weeks later connected to a Mac, what are the consequences? What if the brand new iPod is connected to a Powerbook G4, and then weeks later connected to a new iMac 24"? Would there just be issues with the content on the ipod, or with the setup/firmware, etc.? I received my holiday order including the new iPod and iMac, but am waiting to get some software for the iMac installed. I am chomping at the bit waiting to play with the new iPod (new toys, sweet) (I've been using a 1st generation iPod until now), but don't want to compromise the integrity of the iPod over a couple of weeks.
