It all boils down to what you want, I might be willing to spend premium for a dedicated custom designed hardware made for AmigaOS (the AmigaOne X1000) while I wouldn't use an Open source OS on my sister dismissed PC, which would cost me nothing.
Problem is the design might be custom, the hardware is off the shelf. There is not one specialized chip on the mobo. That would be like bragging over a customized x86 with parts dating back from 2007 (or earlier) is a uber specialized hardware platform to run whatever OS on it. Now I do wonder where ACube's systems come into play since your not mentioning them, they can go pound sand since they are not only for OS4?
It is about what you are trying to offer, what its your vision for the future, those that care to run the official endeavor on dedicated machines don't mind the higher price, they simply find it a more dignified dimension for Amiga to be.
Of course everyone has its own opinion, it would seem that the above one is not much respected though and attacked continuously.
Not too many are attacking individuals who are going to purchase this monsterly expensive hardware. The companies responsible for hype for this machine that the OS can not fully use, OTOH, is fair game IMO.
Get over it. Not everybody accepts Amiga as being a vagrant OS running on other's system scraps (no matter how cheap they are), and are willing to go out of their way for Amiga not to end like that. just respect this simple concept (instead of attacking it continuously) and we will all get along nicely.
I don't see AOS4 users attacking other paradigms on purpose, just when provoked.
I'm sure they would if they have a better bang:buck ratio they could brag about.
