Some CE-related presentations from ESC Boston are now publicly available. Topics include building a real-time system, the debugger, and the CE build system. You can find the presentations here: http://msdn.microsoft.com/en-us/embedded/dd253223.aspx
Some of the demos will also be made available as labs that you can do on your own. I'll update this post with a link once the labs are posted.
Update Feb 2009: Sorry, we decided not post the labs after all due to cost issues.
