I've currently got an iPod Nano and it's only 8GB so it's nearly full so I was thinking about getting a bigger size, probably the iPod Classic if that's what it's called and then giving the Nano to my dad. However the Nano auto syncs with my iTunes library, so if I bought the Classic, could I have that auto sync with my library and then make the Nano manual sync and then how would I remove the music from it for it to be used on another PC with iTunes?
