I don't get the MS strategy. They became popular because they made it easy for developers to build staff for their platform. But then they started morphing their platform into some kafkaesque Labyrinth of new hip and then soon to be retired libs/frameworks. If a developer is brave enough to master this he will then be disappointed trying to monetize it. The Window store (or whatever the current name is) is like a combination of itunes and the play store, but only the downsides mixed together.
