Why Microsoft Didn't Make a Bay Trail Surface | Mobile devices content from Paul Thurrott's SuperSite for Windows

Paul Thurrott accentuates the RT positives (or perhaps the Windows 8.1 tablet negatives?)

"The answer, as it turns out, is straightforward. Microsoft could have done such a thing—goodness knows its PC maker partners are stepping all over each other rushing such products to market as I write this—but is instead backing ARM in hardware for the same reason it's doing so in software with Windows RT: This, not the Windows desktop, is Windows.
More specifically, this new platform—this new Windows, if you will—has characteristics that truly shine (and work) when you don't have a Windows desktop environment that opens your PC up to all kinds of inconsistencies, purposefully or not. This is a version of Windows that will never slow down, that will never succumb to decades of malicious software expertise or poorly-written drivers."
