Subtract the nice wallpaper and the problems here become much more obvious. It's wrong in exactly the same way that the new Gmail UI is wrong. Too much white space, too little colour, tiny grey abstract buttons without obvious hit boxes. Screen elements are too similar in colour to tell where one ends and another begins, white spacing is inconsistent, the scrollbars are too small to grab and lack up/down buttons, the mouse pointer is almost invisible even when placed over one of the darkest areas of the screen. It looks like there's an assumption that third-party programs (Skype) will create icons and front-ends which use the exact same widgets and icons as the new UI, which most of them obviously will not. There's a similar assumption about third-party web sites: what does it look like when you load up Facebook?
How do I launch Office from this interface? What do the tick marks next to "Homegroup" and "SkyDrive" indicate? What about the 3x3 grid of tiny squares next to "Max" in the Skype window, which is almost impossible to see? Why is the "minimise" icon in the top right of all windows still a thin horizontal bar? Why say "thumbs only" when that's self-evident? What do the red and green squares in the IE tab bar indicate? How do I see which taskbar icon is highlighted if my wallpaper is white? How do I see them at all if my wallpaper is bright orange?
