Summary: How difficult or easy will it be to move legacy Windows apps to Windows 8 on ARM? Developers don’t yet know for sure, but theories abound.
Since rumors began circulating late last week that Microsoft might cut the ability for “Desktop App” non-Metro-style apps to run on Windows 8 ARM tablets, devs and users have had plenty to say about the potential significance of this move.
(Microsoft representatives still have not commented publicly as to whether this rumor is true. They didn’t address the issue at all during the December 6 preview of the Microsoft Store, or offer comment as to whether the late February 2012 Windows 8 beta will be available for both x86 and ARM tablets.)
