I sometimes wonder if you are being serious when you write things about the desktop being legacy, clunky, etc. This has been stated before on neowin, but MS specifically stated that the desktop wasn't legacy in posts on their blog (I believe others and I have said as much to you before). It's worth noting that you can't arbitrarily make something legacy when the majority of the user-base, developers, and applications are there. Deprecating the desktop would have meant the demise of Windows for corporate and professional use so I rather doubt that was ever on the table from MS's viewpoint.
I am being serious. The desktop is largely legacy. Win32 dates back how many years now? Computing is moving off in another direction that the desktop just doesn't work with. It either needs updated, or completely trashed all together (hence legacy).
It's completely clunky, there's no unified Control Panel, there's archaic settings, and menus thrown all over the place remaining from only God knows when, and there's registry settings that no one at Microsoft has any idea about anymore.
And if there's still a developer base for it, then they must have one hell of a cloak, because I don't see very many left. Where I work, less than 10% of the applications we run are native, the majority being delivered to users through the browser. In the consumer/educational space, forget it - They're off in Apple and Android land.
Keep on mind, this is just the technical aspects. Windows still has (unfairly) an image problem in the eyes of many people. The idea that Windows suffers from many problems and requires extensive upkeep still persists.
Either way you look at it, Windows as a whole is unsustainable. It either needs cleaned up, or completely re-done, which is exactly what Microsoft was attempting to do with Windows 8.
