I'm not so sure. Granted, I have a .Net past (I currently am a full stack javascript engineer), but I really enjoy the developer experience for Windows Phone - much nicer (IMO) than with Apple and iOS, from a language, ecosystem, and tooling perspective.

My Lumia 920 got here today, and the two gripes I had before - lack of 4g and a pitiful browser - have both been nicely addressed.
