Visual Studio -> iOS + Android
I think Microsoft should purchase the Xamarin company and allow Visual Studio devs to build iOS and Android apps.
There is a real need in mobile to be able to produce apps across all the top devices. Xamarin does a decent job of allowing this but to be officially supported by Microsoft and be able to create iOs and Android apps from Visual Studio would be a dream come true.!
I really think Microsoft needs to embrace the other platforms in order to continue its growth... Microsoft does a lot of things right and by opening itself up to other platforms could be a real Trojan horse. It would bring all the iOS and Android apps to the windows platform which is what Microsoft is really missing...
Besides C# is now far superior to Objective-C and java, and would be embraced by other developers if they could target iOS and Android..
What do you developers think?
