I'm a mobile developer and back around 2011 I was hoping like hell that Windows Phone would make it big. When you look at Xcode (for iOS), Eclipse (for Android and Blackberry) and MS Visual Studio (for Windows Mobile and Windows Phone) for mobile development, there was absolutely no comparison - it was Visual Studio all the fucking way. But Microsoft just decided to completely shit the bed and give up on mobile altogether. I still don't get it.
