My PC, along with an extensive and expensive itunes library, was irreperably destroyed by a virus a while ago, leaving all my songs stuck in my iPod. I'm getting a 17" Powerbook G4 now, so that I'll never have the virus problem again. But from what I hear, Apple makes it close to impossible to transfer songs from an ipod to a new computer-- yet it's the only way to save my music. How can I do this?
