ScottGu's Channel 9 Video on WPF/E and MIX '07
Scott chats with Rory from Channel 9 about the future of Microsoft's web development strategy, MIX '07 and WPF/E. Definitely a great watch.
[Edit] One other interesting topic Scott covers is the low barrier to entry for WPF/E development. WPF/E apps can be built entirely with notepad. XAML and javscript are both plain text. And because XAML is sent as plain text to the client and interpreted there, it's possible to modify XAML on the client, ala WPF/E Pad.
