A simmering battle between two tech giants has boiled over into a an all-out war. As Microsoft tries to regain territory in mobile, maps, and on the web browser, Google is shutting out Microsoft's products from its services. Google's strategy of not supporting Microsoft products like Windows Phone, IE, and ActiveSync could be considered aggression or could be considered not-so-benign neglect. Either way, it has real consequences for both companies and possibly the future of the internet.
