As someone who grew up in the era of PC clones, it's interesting to me to see so much of the interview focus on the IBM vs. Apple angle. Apple was a non-factor in the 90s and IBM didn't have a very strong presence in the consumer market, at least not more than Dell, Compaq, Gateway, etc.
Other than the Commodore 64 that was entry level and about to crash, the winners of the first half of the 80s were IBM then Apple: https://arstechnica.com/features/2005/12/total-share/4/

The Amiga should have been a factor by ‘85, if there was parental supervision over there. ;)
