These huge companies are hard to change. The idea of bringing all the pieces together that Microsoft has at hand should be there for a decade or more. Imagine what Windows Phone could have done with an early deep gaming AND productivity integration with other Microsoft products. However, this years' "//build" seems to mark a real step forward. With stuff like this: Apps that work on all windows devices. No one is excited, because it should have been like this for a long time. But they should be excited, because it is a huge step.
