In the end it's all software running on hardware, I don't care what the underlying hardware is, as long as it works and is reasonably priced...
The Amiga system was an Amiga system, nothing quiet else out there between the hardware and software union. It's a snapshot back in history, there will not be anything like it again, nor should there be.
Today there should be a next generation Amiga OS we could be using. Of the three Amiga-like OS, none of them are next generation. At best there is one maybe 1990s OS, and the rest are 1980s OS trying to live in the modern world and all three are failing at it while the Dev pool shrinks a little bit more.
