A PPC board that runs AmigaOS 4... if you really can't tell the difference between a PPC board running AmigaOS 4 and a generic x86 running Windows 7/Linux and think they're both Amigas, then there's really no hope here. The difference should be blindly obvious to any one.
You are glossing it over. It was a generic PPC mobo with a botched chipset being dumped by the OEM before they went under and the early sales had Linux and not OS4 installed.. I sure can as heck compare it against generic x86 running AROS, both are 1990s Amiga OS like clones, just one didn't have a Amiga badge but ran on better quality, faster, and low cost hardware.
The OS is really the only defining factor in computers these days, Macs are not the same as PCs running Win 7 just because of the hardware similarities, what makes them a Mac? Because they run the MacOS and run Mac apps, same with Amiga hardware, if it doesn't run AmigaOs or Amiga apps, it's not an Amiga.
On the flip side, the currently badged Amiga OS doesn't run on Commodore Amigas. All in all, I don't need a 1990s OS, I need a modern (SMP/MP/MU) Amiga OS and I don't see that coming from the current Amiga community in any of the current flavors. I will wait to see if C=USA can come up with a true next generation Amiga type OS or not. They haven't told us anything about their next generation OS, why damn them before they do so?
