[Dr. Sivana]

As users became more adept , Apple’s closed architecture made PC hobbyists move to what was called an IBM PC.

IBM PCs were well-established before the Mac and even Lisa. What hurt the Mac in the early days was not only the closed architecture, but the cost of configuring a business class machine, and the insistence of Apple to not play nice at the data level with the already established PCs. Mac versions of PC apps were often crap, in part because of Apple's interference (and I am NOT just talking about user interface guidelines). Lotus Jazz and dBase:Mac being two important examples.

The first ones were so dang slow. I remember having to take a coffe break just to change the disk.
