So, instead of trying focus on what kind of user experience we're going to have (which sounds like they think the tablet interface is what people actually want for everything)
Have you seen Win10 preview, or at least read some reviews and look at the screenshots? Because it is exactly what it is about... I mean, the most obvious change that you see once you install Win10 over Win8 is that the Start menu is back. Other changes include things like Metro apps actually running in resizable windows, and the "charm bar" is gone, and all the actions are integrated into the window title bar. Etc... basically, all things Metro are desktopified.
