I believe if Amiga OS is to have a future it has to be available on x86 hardware. x86 rules the market place and will people who have never used it take a look at it? If it is stable, fast and runs their software then heck yeah, people hate Windows for the most part for those reasons and why Linux and MacOS have been growing and Windows has been losing users.
I am not an x86 guy either; x64 is better but I'll always be a RISC guy at heart. x86 is simply the ruler of the market place at this time. If some startup company produced a superior technology (say a Quantum gate processor) with a good OS (like the Amiga OS) and could run users current software, then yes, it could go head to head with the x86 world, but until that day comes, x86 will rule the world.
