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).
The Amiga had good DTP software and hardware at the time. I used them for large format printing. They were initially faster and much cheaper than the Apple solutions.
Large format printing from an Amiga? Surely that is a niche in a niche.
The only pro non Apple DTP people I encountered in that era were Germans with DA's products on Ataris (famously kicked off by an ill considered bet with a Mac owner), and various more workstation or custom hardware type things such as using the Quantel Paintbox for print work, and the odd unix people doing more tech publishing work.
The other thing was Apple became so sticky in part because so many people leveraged Quark Xtensions to a possibly misguided degree, and these proved very non portable. Whole catalogues and directories were being laid out that way.
Fair enough; I guess I'm applying a 2024 lens to a 1988 problem. We don't print a lot anymore, but that I will acknowledge that that was really really important back in the 80s and 90s.
Only briefly. Before about 1988, Unix systems (Interleaf and Frame) were still clear leaders, and then Apple began to stumble from around 1990 - the IIfx was the top of the line for a looong time, and soon looked very dated compared to the 486-based systems selling for a quarter of the price.
But, yeah, for those couple of years the combination of the Mac II, Laserwriter II, and Ready Set Go / Pagemaker / Quark was king. The Amiga never really had a chance to gain a foothold.
