In his article, Thurrott describes Sinofsky as a man with the maniacal power and force of will of a Steve Jobs, but without Jobs' innate understanding of good design.
So what does Update 1 add to the mix? This time around, Microsoft has committed what I consider to be the cardinal sin of Windows: It's a return to that age-old issue where Windows simply grew, spaghetti-like, to accommodate every silly possible need of the system's too diverse user group. Now, there are multiple ways to do different things in Metro, too. These previously consistent environment—like it or loathe it—has finally been put under the committee's knife.
Now, some people will see this as "choice," because these changes—desktop-like context menus in the Start screen, a desktop-like title bar in Metro apps, and so on—will somehow make the system more consistent for them, because they still use traditional PCs. But here's the thing. This mobile environment worked just fine with mouse and keyboard in Windows 8.0 and 8.1, and it was consistent with the touch-based interactions for which the environment was designed. Now? It's a mess.
