I'm looking at a 15" AlBook G4. It is stock, plus Airport Extreme card and 512MB RAM. The blurb says that the screen has been replaced (under warranty, I assume), and the machine has "some scratches here and there", whatever that means. The asking price is CAN$1500 (~US$1215), and local pickup. Is this a good deal? Extensive specs at http://www.everymac.com/systems/apple/powerbook_g4/stats/powerbook_g4_1.0_15.html Thanks.
