I would like to know the possibility of trading my month old Powerbook for a recent PowerMac G5. My PB G4 15" includes 80gb 5400rpm HD, 768mb RAM, 128mb VRAM, Combo drive, Office 2004, with everything that originally came with the PB (manuals, cords, box, etc.) I would be interested in trading for a recent G5. Please let me know what I could potentially get for my PB. Thanks a lot!
