@vesuvius: That's a lot doom and gloom. I happen to believe what ketch just said that WINRT will grow to cover all of desktop apps and Windows 8 store apps. We will all use our favorite managed language to call into the OS. .NET is dead. (long live WinRT)
The doom and gloom comes from the market. The only jobs available now in .NET are ASP.NET, the desktop is in the doldrums and your faith in RT is clearly not based as someone that commissions or consults on large IT projects.
For the hobbyist or semi-professional developer WinRT might seem promising. Show us the Visual Studio 2012 sales, show us no doom and gloom there.
