Microsoft became Microsoft because they were better at marketing/business in the technology industry, not because they were better at building and shipping technology.
Amiga workstations and Macs in the late 80s were way ahead of DOS's UX with its 640k RAM limits and poor CGA graphics capabilities. But they became the standard and caught up with the graphics and multimedia capabilities of the other two platforms 20 years later once they could invest into removing their technical debt.
In contrast, Amiga died a slow and painful death because of mismanagement and owner squabbles, even though they were used for much more than home gaming (real time TV station visuals) even into the early naughties. They were just much better than the alternatives. And ahead of its time as a technical platform and home PC.
