Not that compelling of a demo. I was expecting a little more. For instance, Burton.com's existing site has video and uses Flash.. so what's Silverlight going do provide that will up the ante for sites like that? I guess I know a bit more myself to understand, but from a demo standpoint it would have been nice to hear more about why a design shop would want to switch to Silverlight and show off some thing you really can't do with Flash a little more clearly.
