I just bought an Intel iMac (super nice) and was wanting to upgrade my 15" PB G4 to the new MBP, but money was a problem. The nice thing is, I just got a bonus from work, and it could help a great deal on a new MBP, as long as I can get a decent amount for my PB. 15" PB specs: 1.67GHz G4 1.5GB RAM (PC3200) 80GB 5400RPM HD 64MB ATI 9700 4x SuperDrive Airport, BT Battery still gets over 3 hours of life Still have original box Tiger 10.4 upgrade CD included, iLife 05 No AppleCare Few small scratches on the underside of the PB, none on the top or where the KB/Palm rest is. Just looking for a rough estimate so I know what I should do. Thanks.
