WinRT is just a Win32 wrapper.. just like VB6.
Not as a Flash replacement on the web, but it gained traction as LOB framework. With MS killing Silverlight, and WPF and WindowsForms being on life support, Microsoft has absolutely no credible LOB story! (or desktop applications story for that matter) That's just insane. And no, WinRT is no answer because 1990s MFC is pure sci fi compared to it.
WPF is on life support? Prove it.
