You missed the rumored newcomer to OSes: R-MOS (Root Minus One Systems.) These innovative guys are claimed to be so far ahead of the competition that they've managed to unload one application back onto the user herself.

The full burden to complete work is now back on you, the humble user, leaving the CPU free to fulfill those essential background maintenance tasks without the hassle of dealing with user needs. Of course, some are saying that this is an imaginary OS.

But we're working on it!
