Windows 7 Demo at Tech-ed

Check out this demo by Bill Veghte and friends on Windows 7, Windows Server 2008 R2, and Exchange 14.
This is Microsoft's future platform, which looks to me like it may have a much better uptake than the Vista platform has.
If your product will use these platforms - or your customers want to take you that way - I am sure this is compelling viewing, and you can also download it to watch later.
