Nobody knows these numbers. There are some reports from developers on how much they make from the Mac App Store (for example http://www.cultofmac.com/321860/youll-never-guess-how-little-a-top-10-mac-app-makes-per-day/ http://www.cultofmac.com/321860/youll-never-guess-how-little...), but I've never seen any aggregate numbers. On both Windows and Mac, all big and many small app developers have their own billing and sales. When you buy Photoshop, MS Office, IntelliJ, or even many small tools, then you skip the app store, pay them directly, and download from them directly. So not even Apple or Microsoft know the numbers.
