If only Windows Phone had a greater market share. Despite being a UNIX guy I quite like it plus according to my colleagues (both of which are iOS and Android defectors respectively): You get to use a decent language (C#), Tooling is good and free, Apps are really scary fast, Unit testing is possible, One form factor, Approval is very fast and you can make money as the market isn't saturated to the point the SNR is against you.
Hear, hear. This is just one man's opinion, but Windows Phone 8 turned out to be a shockingly good mobile OS, the terrible market share of which is a combination of being late to the game and being a Microsoft product. It's a little sad that Microsoft's bad/monopolistic reputation of 10-15 years ago still hurts the products it releases today.
Altogether Windows Phone 8 is pretty phenomenal. The UI is head and shoulders above Android and iOS, and the perfect lockstep integration with C#/Visual Studio is a pleasure for development.
