Nerval's Lobster writes "The Surface currently available for pre-order runs Windows RT, a version of the operating system designed to run on ARM architecture. Windows RT looks virtually identical to Windows 8, which, like previous versions of Windows, runs on the x86 architecture that dominates the laptop and desktop market. Microsoft's early marketing materials aren't exactly highlighting that differences between Windows RT and Windows 8 — and as a result, there's a high potential for unsuspecting consumers to end up burned when they buy a Windows RT tablet expecting the complete Windows experience. But Windows RT won't support legacy Windows applications — instead, users will need to hope and pray that developers port those applications to the Windows Store, the only venue for RT-supported apps. Over at The Verge, the intrepid Sean Hollister asked eight Microsoft Store representatives about the differences between Windows 8 and Windows RT, and received several confusing responses. 'To their credit, half of the representatives admitted that Windows RT wasn't as capable as Windows 8,' he wrote. 'The other half not so much. Moreover, those reps who did admit issues seemed dismissive of Windows RT as a whole.'"
