Now that Amigas will not have any custom chip the Os is the only thing that remains Amiga and a Os based around the source code of Workbench - Os 4 -I would argue that is Amiga But an Os based around QNX,Linux or any other Os this is not Amiga
A simple Loop Hole to call a Linux Distro Amiga Because they own the Amiga name a real insult to the Amiga name.
