I'm going away for 1-2 weeks this summer, and I'm pretty sure I'm going to need to charge my iPod a few times while I'm not at home. I think that if you charge your iPod on a computer other than the one that you use it on, it will delete all your songs if that computer has iTunes also. If a computer doesn't have the iTunes software, can you charge your iPod on that computer without it deleting all your songs? Just wondering, because I don't want to bring my big speakers with the charging dock if I don't have to.
