My wife and I recently purchased a new Mac and I have set up my iPod Video in iTunes. I am considering giving my wife an iPod Nano for Valentines Day but am concerned about whether or not two iPods can coexist on one Mac. I have my own userid and she hers. I'm thinking that since, virtually this is two seperate computers that iTunes will see each as one on either userid. Is this a true assumption or is there something I need to do to keep them seperate? TIA!
