Synopsis of "Architecture Guidance for Building Applications in SharePoint 2010" - SharePoint Conference 2009

This was a really cool talk, even though there were no code demos.  The reason I liked it so much is because I didn't know about all of the different application patterns that they went over.  If you don't know about these SharePoint application patterns, then you had better make sure you watch this video, or you might get left in the dust.  It was a lot to take in, but they gave us a nice intro, and pointers to resources for further study.
