MS beats apple to the punch with a ARM powered (full) OS
With all the rumors of Apple switching to an ARM based architecture for Mac OSX, it is funny that Microsoft already beat them to it with Windows RT.
Windows RT of course is basically Windows 8 for ARM devices. Perhaps with a ARM based Mac OSX Apple would choose to emulate x86 for older apps/programs, something MS declined to do. But still, it is impressive that Windows RT has virtually all of Windows 8’s functionality (sans legacy software compatibility) whereas Apple only has Max OSX for x86 and iOS for Arm… two wildly different OSes when it comes to functionality, file manipulation and expansion.
The end result of all of this is that PC manufacturers could for the first time ship devices slimmer/cooler-running/longer-running than anything Apple could get out of the comparatively power hungry x86 devices.
