Neowin blog article notes UI Advantages in “Windows 8 and Why I Love it article”
QUOTE: While I’m not against change for the most part, I can understand why people get very passionate when something so ingrained in their lives is taken away from them. By this I am talking about the decision to remove the Start Button from Windows 8 and Windows Server 2012. I can also understand that the alternative the same people are then presented with just doesn’t do it for them. I am talking about the Start Screen and the Modern UI that Microsoft has brought to their Windows OS.
And what of the UI on the traditional desktop? Aero has been semi-retired in favour of, the Modern UI. Obviously, the first thing you see is a clear lack of Start Button. But the Taskbar remains the same as Windows 7. What we get is the last remnants of Aero Glass transparency on the Taskbar, square corners to windows and square flat edges to tabs in the Ribbon interface of the desktop apps. Curves are pretty much ignored. While the desktop and Start Screen are different experiences, it’s all been done to blend the look of both that little bit more. Personalization remains the same as Windows 7, being able to change the theme, wallpaper, font & icon size, it’s all there. Microsoft has even bundled in a panoramic theme, Nightfall and Starlight, to show off the desktop across multiple monitors.
