For me it is of a great interest, I always said if MS released Windows for arm as an open platform as with x86, it would be a bomb. Arm finally could enter a real competition with Intel. Not a locked down and sythetically limited version, but full and open for development, - drivers, applications... I am too busy to follow things. :/ The arm ecosystem is too undeveloped now, there is no standard firmware on it, no ACPI out there for now, it would be not easy to get it on every board as with myriads of x86 motherboards. Things are changing and sooner or later it will be that. So even if Allwinner chips will not be the first getting support. they will get it anyway. With an open for development Windows, it would be more up to Allwinner (Rockchip, Amlogic) in fact.
