That's a different issue: SIMULTANEOUS multiple users. I would still argue that, for an OS to be "state of the art" (as was claimed by the original poster), it has to have some concept of file ownership; a multiple user model in which a user "owns" a file. If my friend sits down at my Amiga and works for a while, I want reassurance that he cannot accidently delete my files, NO MATTER WHAT. This is what I mean by "multi-user capabilities" -- that several people can use the same Amiga (not necessarily at the same time) and nobody has to worry about corrupting another person's data. I claim that an OS without this feature is not "state of the art". That's all I'm claiming -- no more, no less.
