I know the powerbook is rather archaic now, but I'm trying to get a new Macbook and don't want to throw my old powerbook away. So.. I have a friend who wants to buy my old G4 Powerbook with 60GB capacity, 512 MB memory, 1.33 GHz cpu speed. It's extremely worn in, meaning, it won't last more than 20 minutes off the power cord, but someone could always replace that. So what would be a fair price to charge someone to take it off my hands?
