The desktop view looks virtually the same as Windows 7, so I thought I'd post my start screen:
As you can see, it's nothing particularly exciting. It's clean and functional. I'm still not a great fan of the tiles for non-Metro apps, though based on the article posted on the front page a while back it looks like they'll be overhauled before release - larger icons and smaller text will be much appreciated. Overall I like the new start screen, as I find it quicker to find and launch apps (you can fit a lot more apps in than the Vista/7 start menu).
