Thanks for the clarification. When I read WinRT, I thought it was shorthand for "Windows RT".
Knowing that, I'll stand by my original comment and clarify that I meant "Windows RT", the tablet OS that looks and feels like Windows but won't run regular Windows apps like a Surface Pro can (or am I mistaken about the Surface Pro too?) then it needs to go away or a name change. It generates confusion. I mean, the difference between Windows 8 and Windows 8 Pro is the feature set, but they run the same applications. The difference between a Surface and Surface Pro is much greater than that, unless you consider "running the same applications" just a "feature."
