You know what? I had completely forgotten about the Amiga. (Duhhh!) The Amiga did make a pretty good splash, AND it carved a niche for itself in the video processing area that even Apple couldn't penetrate. There were quite sophisticated gadgets available for the Amiga which you couldn't use with a MAC or a PC/AT. What's more, the "fancier" Mac's and PC's didn't make any headway in that arena either, as demonstrated by the lack of competition with the "gadgets" needed for some of these tasks. There was, of course, a major difference between the earlier Commodore products and the Amiga. A look under the hood would quickly reveal that.
