The profesional publishing revolution was on the Macintosh. I worked in that industry and I experienced it. The Apple LaserWriter was a proofer the size of a washing machine and cost more than a diamond engagement ring and it probably hung off a Mac II running A/UX and acting as a (Appletalk) network spooler. That's not the stuff of a desktop revolution.

The desktop publishing revolution came when average Joe Schmoe could whip off a (almost) professional-looking typeset zine on his home desktop computer. That was An Atari ST, and Atari SLM, and Calamus.
