Shirley I agree with everything you said except the quoted statement. The iPod has a large buffer (I don't remember exactly but 32 mb seems to come to mind) and the idea is that the hard-drive only spins when the buffer needs to be replenished. So if you play long selection or don't change the play list that was selected the hard-drive is used as little as every 20 minutes or so but if you are constantly navigating to select different playlists, artists etc. you will force the iPod to use the hard-drive more. Gerhard P.S. I bought a mini iPod for my wife and she loves it, uses it to play mostly 50 - 70s music in her car through a cassette adaptor.
