I've just bought an old PowerBook G4 precisely so that it could boot Mac OS 9 and I could install some old programs to play with. As I switched it on to see if it's OK, I was impressed by how quickly it started up its current Mac OS 10.4.
I still think classic Mac OS was a truly gem of UI and UX and things just went downhill from there :)
