The developers of Arix are solving the driver limitations by using one of your hated linux kernels. And I have to say that I know a lot of people owning X86, using it on desktop and/or server with none catching fire so calling it "junk" is nonsense. You have a huge market with lots of different components you can choice from so if you need something 24/7 you use different components. And I have one customer where a normal "junk" PC run since 2006 24/7 without any failure or "catching fire".
I'm the lone IT person at a large government office. I take care of 100's of x86 machines and not once over the years have I ever had a machine catch fire. X86 machines these days are far from junk. And I'm also looking forward to what the Arix guys come up with.
