I'm impressed by the fact that they used Silverlight to highlight Bill Gates keynote and Microsoft at CES. Note that the intro is a bit long before they actually let him speak. If you'll notice at the bottom, they included all of the tags for their products they are highlighting. The only logo I questioned was Microsoft Office. How in the world is Office linked to entertainment?
I think my favorite bit was about Microsoft Bob
