I have some questions about using multiple computers with my iPod. 1. I would like to plug in my iPod at work to keep it charged. But it keeps loading an old version of iTunes (is that on my iPod?), and telling me to install the current version. I don't have privelege to do that. 2. When I connected it to my 2nd computer, it asked for my Apple ID. I'd like to use someone else's laptop on a trip to charge my iPod (and to watch videos). But I don't want to install my Apple ID on that laptop. Is that possible? 3. My wife has enough money for half a Mac and expects to buy a Mac in March. I expect to have money in about a year. If we go Mac though, it appears that I won't be able to plug it in at work at all. Does Apple have any plans on making iPods compatible with mixed systems - or are they figuring that our switching to Macs is a dumb idea?
