I adore early tech, or at least the history of it. All the nostalgia, and I really miss the excitement of new tech when I was a kid. Still, I'm having a tough time imagining a niche for this. It's an expensive machine (especially given the hardware). Apparently AmigaOS is available separately for about $30, although I haven't looked at the hardware compatibility. Still, kind of a tough sell.
It looks like a cool machine. All the efforts to resurrect Amiga have been pretty cool. They just have the BeOS problem of not having any applications. Amigas were big in TV production way back when, but kleinbl00 isn't going anywhere ProTools doesn't run now. The Xena thing might have been neat for scientific computing if it were 20 years ago and GPUs didn't do it better. It's hackable, but so is Linux and it has an ecosystem. You can run old Amiga games, but there are Amiga emulators for every platform. The demoscene will have fun with it.
When Amigas were king we all ran hardware. None of us want to go back. Fun fact: Commodore became a video computer rather than an audio computer because the guys who did the audio chips on the C64 and Vic20 ran off to form Ensoniq Which tried to make a run at Pro Tools with the Ensoniq Paris Which ended up being bought by Creative Labs. So really, the lineage for the early days of Commodore computing is Soundblaster. I still mourn the death of BeOS and I never even got a chance to play with it. Yes, I know there are emulators. That is not my gig. I'm currently wrapping my head around writing Dolby Atmos from home.
