Risky in a legal sense maybe? It seems to me Microsoft has been really trigger shy about pushing forward on integrating all their various services and non-PC products closely with Windows due to their past problems with DOJ/EU. I feel like if they made a big push to integrate things like Zune Pass, Xbox Live integration, Windows Phone, cloud services, Bing search/maps, etc they would have a much more compelling platform. All their competitors are doing it so maybe they now have the cover they need with the DOJ/EU to wrap everything together.
