I have to agree. The PowerBook 140/160/170/180 was a nice piece of industrial design. The way that the battery door acts to lock the case halves together makes it impossible to disassemble the machine with the battery in place - someone thought about that bit and got it right.
The PowerBook 100 wasn't too bad, but had a cheaper plasticy feel to it.
The Duos were good to work on, given their size. I always hated taking the middle hinge cover thingy (forget the official name for it now) off though. That bit was just nasty and I always had to keep a new one in stock for if/when someone damaged one taking it off a customer's machine.
