I'm certainly not the first to suggest this, but perhaps hearing it from more and more critics will drive the message home. Microsoft needs to stick with the Modern (formerly Metro) interface on Windows RT devices like the Surface. That means no desktop. You shouldn't have two completely different computing environments on the same tablet. In order to unify the user experience, though, Microsoft will need to get Office to work within the Modern environment, as well as create a file manager that works in that mode. Microsoft would also need to beef up the settings menu in the Modern UI to obviate the need for a desktop.
