I wish I hadn't seen this post. Now I am scared, if that's what the new MS Office will look like. The toolbar looks like it's as tall as a basket ball player, and it'll eat most of my 1024x768 screen. I hope that KDE/GNOME won't adopt it. Don't get me wrong, I do like different layouts for apps, I like the Kids Office plans, but such layout could be really difficult to use in a INATAS enviroment. And I'd have to use a magnifying glass to see the text in the menus/toolbars.
UPDATE: Correct link.
