I'm not complaining... just observing. I'm not one of those who pines for the "good old days" of cooperative multitasking, unprotected memory, and application errors taking down the whole system.
Although I do find it remarkable that they were able to stuff so much into such a tiny amount of space (everything had to fit on a 400KB disk plus the 64KB Toolbox ROM, and the OS plus applications only had 128KB of RAM to run in).
The OS is bigger but it sure is more capable.
