People always mentioned killer software like Studio and Office, forgetting that one just doesn&#x27;t rewrite software like that.<p>For example Studio is still 32 bits, for many reasons,  one of them being third party plugins that no one is going to re-write.<p>Windows File Explorer and Edge are two UWP applications on Windows 10.<p>Having separate XAML for mobile, tablet and desktop is no different than responsive HTML, with the benefit of being native.<p>But what can I say, I love WinRT as it feels C++ Builder is vindicated.
