Whiteboard with Anders Hejlsberg is a must-watch video from an informal presentation he gave at TechEd 2004. The conciseness, clarity and depth of knowledge is impressive. He covers a range of topics and talks about design decisions that were made to help us understand why something is or isn't part of C#. All I can say is I want to be like Anders when I grow up. Hmmm. Probably too late. :)
