Again with the dead horses...
Look, to everyone screaming about OS4 on X86 hardware... WE ALREADY HAVE IT!!!!!! It's called AROS. Look into it.
AmigaOS 4 and higher will, and should, remain on PPC processors untill the EOL of the architecture. Period.
What I don't understand is why it seems to be so hard to get OS4 running. Hardware for it has existed for YEARS. There are numerous manufacturers of PPC motherboards out there. Pick one. Pick several. In fact, pick them all! Forget this product licensing BS. We don't need dongles or any other anti-piracy crap. Anyone who would even consider buying a PPC board for the purpose of running OS4 would buy it legitimately. But if that's a major concern, force registration. That'll solve most of it. Anyone else who wants to run it bad enough WILL circumvent ANY form of anti-piracy scheme. There is nothing that cannot be cracked.
The long and short of it is, OS4 is not meant for joe user. It's meant for US, the Amiga community. It should be opened up to what WE want to run it on... Like the cheap and sexy Efika.
