> My own impression for why the Amiga and every other machine of the era lost out to the IBM PC was that the PC was what virtually everyone used at work, so that's what they got at home.

And it was also what you were taught on at school. Even if the IBM PC advanced the standardization of personal computers, I feel it also set them back by a decade.

Well, a decade is exaggeration, but the design choices of the IBM PC shaped personal computing, and those choices were made by people who thought personal computers were for serious business.
