Ok so, i have been looking around for a Powerbook to just toss around I was thinking a old like first gen Powerbook G4 but as i look I notice that people still want an arm and a leg for these things I've seen 400MhZ models go for like $990 I could buy a new iBook for that anybody have input on why these things are worth so much?? I have a few ideas and want to know if they are the same.
