I have several computers in my home, because sharing computers leads to arguments. At the maximal sharing, you'd have several people, sharing a machine, at different times. It isn't a mainframe.I'm thinking multi-user and I can't fathom why anyone would ever want that. Can someone enlighten me?Two users at the same time, on the same computer, using different monitors and mouses but sharing the video card. I'd say that's an unlikely situation, however.
