.NET Show: Longhorn overview

MSDN: "In this episode of the .NET Show, we will provide a general overview of the larger technology "pillars" of Longhorn,introducing you to their concepts, as well as showing you some of the coding techniques for gaining access to them." I've seen it and it's a good place to start to learn about the new Longhorn pillars if you don't know much about them. Personally I haven't learned much new.
