I don't know a lot about iPod. I do know, though, that I have somewhere between 500 and 700 CDs in my collection, and carrying them all around is out of the question. What will often happen is that I'll have an urge to listen to something specific and be nowhere near my CDs. It would be nice if I could store all that music on a little portable device that I can plug headphones or speakers into (or that I can somehow interface with my truck's stereo system) and be able to listen to anything in my collection whenever I want. And I don't want to spend $400 for such a device.
