No idea where MS is trying to go with RT. It's a Dodo bird in progress imho. What makes the Surface Pro great is that it's a real computer that can run all desktop Windows applications. The RT is just a wannabee IPad, and is doomed to be only marginally successful (like Windows Phone) because of the lack of apps, an established iOS ecosystem, and people's existing/previous positive experience with the IPad. I think Windows Phone is great, but it fails to provide any substantial value add over iOS, and hence there is no incentive to really switch. Same with RT.
