I'm a bit late with this, but the PowerBook 100 made it to number one of Mobile PC magazine's Top 100 Gadgets of all time. Obviously, I have good taste. I've got a PowerBook 100 sitting in a cupboard, and it was the machine — bought second-hand — that I wrote my thesis on. I was very fond of it, despite the persistently squeaky trackball that I never managed to silence. I slaved over it, played an inordinate amount of Tetris on it, and it even survived having a terracotta plant pot fall on it — a tough little machine.
