I think this Amiga version of history ignores what Apple was good at by the late 80s: DTP. We collectively seem to have forgotten what a huge deal this was, laser printing, postscript etc. It genuinely overhauled the entire publishing industry, not entirely for the better either.

By the mid 90s Microsoft were persuading a lot of people WinNT would displace Apple in publishing, but that never quite worked out how they intended either. (This is one of the reasons Xara was developed on the PC and not the Mac, which with hindsight was a big mistake).
