So you're saying you're a "developer" that was using iOS, planned on going to the Nexus and then you just decided to go to windows phone after playing with a Focus S and now after getting your new phone suddenly you're going to start developing for windows phone. Sure.
I started my career as a developer working on the Microsoft platform. In fact, I'm probably still most comfortable in C# more than any other languages. My current job I work in a mixed environment of C#, Java, and Ruby. I'm not sure why the sarcastic comment without knowing my history as a developer?
