Intel hardware to become windows-locked so you won't be able to run any alternative OS.
I don't think windows will run on UltraSparc and I doubt it runs well on Arm.
There have been headlines for some articles that implied that the latest Intel processors would only run Windows 10. My first thought was Apple might have to build Windows 10 machines or get a different company to make its processors.
