Before heading over to Barcelona it looks like MS put together a news video with Channel 9. This shows you a great actual demo of how Windows 7 works between moving in and out of applications, the web browser, searches, etc. It opens in Windows Media Player and you can also see parts of the OS that are still in development. Check it out here. It’s about 20 minutes but it’s probably the best overall view of what this is all about. Other things that are notable are that you can flip from black on white to white on black depending on the type of screen you are using. Pretty smart.
