Windows For devices has posted a chapter of Jens' new book to help readers evaluate if they want to purchase it. Here's what Jens had to say about it in a recent newsgroup post:

Expert .NET Micro Framework will be published end of April and is available
by preorder from the publisher's website at
www.apress.com/book/view/9781590599730, or on Amazon at
www.amazon.com/Expert-NET-Micro-Framework/dp/159059973X/ref=sr_1_1?ie=UTF8&s=books&qid=1207137527&sr=8-1.
Meanwhile, you can get a sample chapter from the WindowsForDevices website
at www.windowsfordevices.com/news/NS9490079215.html.
Chapter 4, "Introducing the .NET Micro Framework base class library" reviews
the differences between the full .NET Framework and .NET Micro Framework,
explains how to effectively use strings, numbers, arrays, and lists, and
shows how to handle exceptions.

I've always liked to be able to review the table of contents and at least a portion of a chapter to get a sense for an authors writing style and the level of details covered in the book. (e.g. If I buy the book will I be drinking from a fire hose or a water pistol?)
