After what I am sure is  a lot of labor and work Jens Kühner has finished his book on the .NET Micro Framework titled: "Expert .NET Micro Framework" you can pre-order it now on Amazon. Jens has been quite active in the Micro Framework focused newsgroup and clearly has a real world grasp of what the framework can do. I'm excited to see what he's written in the book and what new projects/products it will help to inspire!
