It only started working at all, late last year! As I'm on the Dev-list I can see the improvements daily, with our support it will surpass the aged Commodore produced OSs
Right, so my point is, until you can provide a 100% (or even 99%) compatible Kickstart replacement and AROS 680x0 package then it doesn't enter this discussion. We may as well be talking about Cold Fusion.
Don't get me wrong, I'd love to see AROS appear as a modern compatable Workbench replacement, but it has been something like 20 years so far and it still isn't there and I'm not prepared to wait another 20 years for it to mature.
I've always got the feeling that AROS is about pushing the Amiga OS onto other, faster hardware and 680x0 versions are a bit of a sideline.
