As a footnote to history, Manx Aztec C shipped with a complete set of Unix-like tools for non-Unix systems. This included a partial VI clone of their own. So users of Aztec C for MS-DOS, Mac, Amiga, Atari-ST etc all got VI clones as part of the deal.
I have been a VI user my whole life as a result (I worked for Manx in the late 80's, and their flavor of VI was my first real taste of text editing).
