Ami Pro on OS/2 was my word processor of choice through most of high school. The intuitive layout controls and clean, focused interface spoiled me for life.
Word docs being the medium of exchange created enough of a network effect. I remember trying to use other programs but importing/exporting to Word wasn't perfect.
Windows 95/98 shipped with some kind of half-implemented Word, the name of which I forgot. So you could send a Word doc to anyone basically and they could read it, a great business strategy.
