I should be able to delete all my music off my HD and just leave the Itunes library list and my Ipod will still sync correctly, yes? See, I want to update my podcasts, add photo's and video, movies to my 80 Gig Ipod, but can't afford the real estate on my 17" powerbook HD. I remember last time I synced with my nano over the summer I had deleted all my music, but not cleaned out or updated the library and I was able to sync to my Nano without it affecting what was already on there. It just added the new stuff. Confirm?
