Good/valid point by Paul Thurrott: RE: Surface 2. The very last sentence says it all. "... This, not the Windows desktop, is Windows..."
Why does Microsoft continue to invest in the ARM chipsets that don't run traditional Windows desktop applications? Why couldn't it have made a version of Surface 2 that runs on the Intel Atom "Bay Trail" processor instead?
The answer, as it turns out, is stra...ightforward. Microsoft could have done such a thing—goodness knows it's 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.
