I’ve been at MGB (in Atlanta) this week, and as you should know by now Windows Vista (formally Longhorn client) has been announced.  There is a video to watch and a beta to expect.  I spent a few hours today in a room full of Windows Vista machines, some time was spent listening and following a instructor led demo then we got some free time to explore the features ourselves.  Sorry I can't divulge the great new features available…but the beta is coming soon!
