I think if Microsoft doesn’t go this route, ARM for Windows is just dead. The cost of Windows 10 ARM PC’s is too high, the performance too low for the cost, while compatibility is still not great. Bringing up lower-cost ARM PC’s to run Windows 10X seems like the logical way to combat Chromebooks if this is Microsoft’s target market. They should be able to guarantee a fast, possibly fanless system not bogged down by Win32 legacy, and provide long battery life for the education market. They can add the Win32 compatibility container later for real x86 PC software compatibility.
