So now the preview is up. There is the question about how the task tiles will look when there are more than say 4 or 5 of them. The thing is that the preview is for a width of 1024. Most people can run higher resolutions than that. Also the taskbar can be placed alone without the other sections or with those sections somewhere else. This reasures that the tiles will look good on a screen with resolution 1024 or even less.
