Very rich person toy!
Not only had computers not become a household item, but for those who were interested enough to buy a home computer, there were many different brands and models to choose from, most at a fraction of the price of the Apple. The computers I actually saw in the 80s were Timex, Toshiba, Sinclair, Commodore, Tandy, BBC, Amstrad, Archimedes. These were pretty much all separate ecosystems, with different models from the same manufacturer frequently being incompatible with their stable mates. Considering how capable machines like the Amiga and Archimedes were at a fraction of the cost of the Apple, and considering the fact that Apple was just another expensive ecosystem, you had to be particularly loaded to buy into it. Was there a must-have piece of software that only existed for the Mac back then? Computer graphics was arguably better on the Amiga, and even desktop publishing wasn't a done deal.
I know of only one person who had a Mac, and it was loaned to him by the company he worked for (as a software developer). No idea why they chose Apple.
The first "PC" I ever saw in real life was a Wang (unknown model) some time in the very late 80s. that was purchased for our school tech drawing class. It ran DOS and AutoCAD (unknown version) and also had Prince of Persia.
