This promotional video for Internet Explorer 9, from Microsoft Finland, is pretty cool. It shows how IE9, Windows 7, Bing and Windows Live all work together for social networking and media sharing.
The on-screen text is in Finnish, but you don't really need to know it to get the message. Google and Bing translators suggest the tagline at the end means something along the lines of "companion for life."
