This last weekend I did a run up to the Oklahoma City Code Camp to give my "Introduction to C# 3.0" talk in the morning.  I got to attend the keynote talk given by Jason Zander and it was great.  He did a very good job showing off how XAML (be it WPF or Silverlight) allowed for powerful and graphically inviting UIs while still allowing developers to work in a way which they are accustomed to.

Unfortunately I did not get to stay for the full day, as personal obligations called me back to Arlington.  Still, if you get a chance to attend a Code Camp in your area, I would definitely go.  Likewise if you have a chance to hear Jason talk, I'd go out of your way to make sure you do.
