Windows Universal Apps

I had plenty of work with my PhD studies and my job so I had not had time to install Visual Studio Express. But on the Build conference, Microsoft showed new Windows' features. Updated Visual Studio can create universal apps for both: Windows 8.1 and Windows Phone 8.1! Although I have not had time to tinker with it long enough, I have managed to create a universal hub app, build it and run on Windows Phone Emulator. And it worked! But after looking into Solution Explorer:

 I have noticed that the Universal Windows Apps are not something entirely new. They are based on an idea, which was known at least from the time when Visual Studio 2013 was published! It was presented on MSDN: share common code and use a separate project for presentation only. Updated Visual Studio mostly eases create of the separate project and shared library and debugging code for the Windows Phone. Although it is not a revolution but an evolution of ideas known for some time, it is welcomed. Maybe it would allow consistent experience across different Windows platforms and faster apps delivery!
