Here's a minor iPod annoyance - every so often, when my daughter has left iTunes up, and I attach my iPod while I have iTunes up, the iPod decides that it should try to attach to the other instance of iTunes. This is annoying, because I have to get my daughter to come in, have her log in, eject the iPod, and quit her instance of iTunes (otherwise, it's just "rinse/repeat" time). Shouldn't the iPod know which library it belongs to, and attach to that one? It's smart enough to tell me it isn't synched with the other library, so why can't it look at other running instances?
