I have a dinky little G4 iBook with only 30 gigs on it. What I'd like to do is get a 30 or 80 gig iPod and dedicate that exclusively to my music and video, playing it directly from there. Is this possible? One difficulty I don't know how I'd get around is the fact that every time I play a song from anywhere on the computer, iTunes automatically saves a copy in the iTunes folder, so I'd have to either turn that off or have it so the iTunes folder is on the iPod itself. Can I do this? What do you think?
