We’re also excited about the thriving ecosystem of developers writing apps for Windows Phone. This week, we expect to exceed 16,000 apps available in the Windows Phone Marketplace. With new capabilities for developers in Mango (e.g., HTML5 support, Targeted Distribution of apps) we expect an even larger number and wider range of apps for Windows Phone in the future.
