Hey everyone, saw the best and worst computer you've ever owned topic, and it brought me to wonder what the best and worst PowerBooks Apple ever made were. For me, the greatest 68k based PowerBook would be the 180, the worst 68k PB - the 150. I have a soft spot for the 180. As for PPC (5300 to date), I'd say that the Pismo G3 chassis is the greatest PPC PB, while much maligned 5300 would be towards the bottom. Just marginally faster than the 540c, and not as well equipped.
The iBook (dual USB and subsequent models), titanium and aluminum PowerBooks are great, beautiful, wonderful machines, however they show dirt and wear much moreso than any previous laptops. The iBooks (dual usb and G4 12") I've owned have driven me insane from how the polycarbonite scuffs. As for the PowerBooks I've had (AI 12" and 15") every scratch was heartbreaking. Short of how fragile the aesthetic values of the PowerBook G4 and iBook (dual USB and G4) and the tortured ergonomics of the PowerBooks (wrist rest digs into my arms), they may be the best machines Apple has ever built.
