Windows 2 was an interesting moment in computing history.

Microsoft wasn't the dominant player and was sort of the underdog in many ways. Lotus was usually considered a more important company (Lotus 123 was huge) and WordStar dominated word processing.

The idea of the office suite hadn't taken off.

There were multiple competing GUI shells (GEM was popular and considered better than Windows).

Other non-PC, non-Mac computers were legitimate choices. Commodore, Atari, Tandy, Amstrad all had non-PC lines that sold really well.
