I never intended to recommend those programs for everyday use. Rather, I simply meant to point out that office software was already becoming popular by the time Microsoft Office was released. That said, you previously mentioned this:
I mentioned those old programs in an attempt to debunk that claim. Many people had already stopped using typewriters by then. Even without Microsoft Office, people would have stopped using typewriters eventually. Maybe they would have used something like Star Office or WordPerfect instead.
Of course, that didn't actually happen, but it could have if MS Office didn't exist (or somehow became a commercial failure).
