amigazone,
Lets face it... A PC is nothing until its been loaded with an OS... why cant that os be AmigaOS
As far as OS4 goes, Hyperion has made it clear that even if they wanted to make an x86 version of OS4 they can't because they only have license to make PPC versions.
Don't even think about the PPC Mac either! For some reason Hyperion can't get the mobo documentation needed to support PPC Macs. Besides, the PPC Mac is no longer in production and Hyperion has stated that they "aren't targeting the 'have a few spare PPC systems lying around' market". New PPC hardware must be custom-built from the ground up for OS4, and it must also be expensive, slow, and hard to get. I know it all sounds crazy, but you'll catch on soon enough!
But like I mentioned before, AROS is free and runs on PCs.
