They're trying to sell it as a sort of entry point into the modern 68k Amiga ecosystem for enthusiasts as well as a plug-and-play gaming box, but I feel like both niches are well covered by other devices.
* The more expensive tier is apparently going to have DB-9 ports for classic Amiga mice and joysticks, so there's that... I guess...
Think C64GS, Amstrad GX4000.
Don't know which sbc it is, but it looks pretty simple, with the db9 looking to perhaps be a daughterboard/hat/extension hooking up to GPIO type connectivity at a guess
I suspect most of the development is in the software with the GUI, and licensing various packages etc.
Then someone saw a business opportunity putting a dirt cheap arm board with Amiberry preinstalled in an Amiga500-shaped box, without crediting anyone or anything. And they sold a bunch of them. That's Amiga 500 Mini.
Now I guess AmigaKit, looking at that, wants to make bank too.
TL;DR: Just use the open source Amiberry on the Raspberry Pi it is meant to run on, and don't give these scavengers your hard earned money. Alternatively WinUAE, fs-uae, MiSTer miniMig core.
