The compatibility comment in the article was interesting. There was definitely a period when bug for bug PC compatibility was not widely appreciated by a lot of companies because it hadn't historically been a thing. Even Corona had a weird one-off monochrome graphics mode that basically no one supported (and made it incompatible with add-on graphics cards like Hercules).
I think it's also easy for people to forget that in, say, 1982 if you were shopping for a computer a PC clone wasn't necessarily the obvious choice.
