in CP/M there were "users" too, but it was just to help keeping it clear, 
not for security, you could simply type user <n> to switch users AFAIK.

even really understanding it, or if they did - simply ignoring things.

i never used OS/2 for really long, my friend was. it was faster than FAT 
by much, and never had FS crash.
