But Apple had hardware as well to support their Unix driven OS, giving some identity to the whole thing.
An Unix based Amiga OS is still uninteresting to the average Joe imo.
I see two variants of the Future Amigas:
The classic one: Stuff like Clone-A and to a lesser extent the Minimig, blown up as hard as possible for performance and being able to connect to more modern peripherals like VGA and PS2. Imagine a monster turbo classic AGA Amiga with a proper gfx card already built in and some other goodies. I think a lot of people would like that.
The modern approach: AROS on PPC or i386. I simply don't see Amiga INC in Business a few years later, and i cannot imagine Hyperion, even if they win the court case, to go on working on something as niche as an Amiga OS by themselves one more time for OS 5. So it's open source AROS, or nothing.
