I disagree with the "Microsoft platform" bit. The Mono/Xamarin guys have been coming up with a very nice competing/complementary platform. I've built personal and production projects running on Linux using Mono. While I haven't used, the Xamarin iOS/Android development platforms look quite interesting. I suppose it has the stigma of a somewhat pricy per seat license but its likely worth it if you want to go with a shared codebase for iOS/Android/WP/Win8. There's also MonoGame[1] which targets developers of MS's former XNA game dev kit. [1]http://www.monogame.net/about http://www.monogame.net/about
