Just like the Windows Phone 7.5 Unleashed book, everything about this book rocks!!! It is in color which makes for a great read. Being able to see the code and screenshots in color doubles the value of a book like this. I wish all programming books that included coding client UIs were in color.
Although the chapter names usually highlight the main topic covered in the chapter, some chapters like chapter 2 cover a ton of topics. It covers XAP files, the capabilities model, threading model for graphics and animation, the frame rate counter, performance tools, how to determine device status, MVVM, commands, and a platform-agnostic dialog service.

One of the things I really like that the author did was introduce the Windows Phone Performance Analysis Tool right off the bat in chapter 2. Knowing how to make use of the performance tools may really help developers without an actual device.
Another thing I really liked was that the author made use of MVVM throughout the book. He did not just introduce it and then continue with the rest of the book without it, like I have seen done with some other XAML books, he made extensive use of it.
The author does a great job covering the Windows Phone Toolkit. He covers the ListPicker, AutoCompleteBox, ContextMenu, DatePicker and TimePicker, LoopingSelector, Page Transistions, TiltEffect, ToggleSwitch, WrapPanel, GestureService, and GestureListener. He does not just list them, he provides in-depth examples of each.
The chapter on Building Location Aware Apps is not only a great introduction to Bing Maps, it also contains a practical example of using Reactive Extensions (Rx). The chapter on Geographic Location also contains a nice example of Rx.
The chapter named Processing Touch Input is all about gestures. It gives a great overview with some really good visual aids. It covers all the gestures and their associated events.
The chapter on Launchers and Choosers is awesome. The author does a great job of covering a ton of them. He covered so many of them, that I am not sure that he missed any. He provides a nice code sample for using each one.
The downloadable code is very well organized and usable. I did not run into any trouble with the samples, which is amazing because there are a ton of them.
Every chapter of this book is rock solid and they all go in-depth. The last thing I will say I liked about this book is that it took advantage of tools like LINQ to SQL, Odata, the Unit Testing Framework, and Reactive Extensions in practical real world examples. The author doesn't skimp on implementation examples.
All in all if you are considering getting into Windows Phone 8 development, or are already involved with it, this book is an absolute must!!!
