What MS is saying is that they can get more quality out of WXGA with RT than Apple does out of QXGA with iOS. Which may very well be literally true but doesn't address the basic fact that Windows RT could get even better quality out of a FullHD panel.
There is a difference between getting the most out of a lower resolution panel and offering up a higher resolution display.
One area where native higher resolution pays off is in HD video playback where displaying a full HD stream at native resolution will stress the CPU/GPU less than scaling it down for display on a lower resolution display.
Obviously, a corporate PC will care less about resolution than a media pad since HD video playback isn't mission critical at most corporations.
But for some consumers...
