Holy Moly.. I simply can't believe how poorly written this book is. The first few chapters are readable, but the farther you read, the worse it gets. Here's a sentence that perhaps Yoda wrote on page 488 of Chapter 10 (3rd para) "The answer is to that no." That is also how I'd respond to ANYONE asking me whether or not to purchase this book. FYI: I dislike code examples that drag along for hundreds of pages (ie. Mortimer Phones). It is possible to come up with an example to demonstrate a principle and then start clean for the next topic.
