Dean Takahashi is a reporter for the San Jose Mercury News. While I applaud his efforts to do the research and leg work to uncover the history, back story and technical details of the Xbox 360, this book just simply is not well written. Dean does a nice job in news reporting related to the tech industry and gaming in general but he is no novelist. This book is obviously not a novel either but you might expect it to be at least a story...In my opinion, it is not- it is a collection of observations loosely tied together, and even then, it is flawed.
As other reviewers have noted, you will find yourself reading the same information, names, and sometimes even quotes in multiple places throughout the book, making it harder to follow his line of thinking clearly. Oftentimes, there is also a bit much of the delineation of who worked for who and who quit the Xbox team when, etc. that does not really lead the reader anywhere or add much to the story. To me, this book feels similar to the previous Xbox book written by Dean in that way- some great tidbits but overall, barely worth reading because of how painful it is to get through it. I've never had this situation happen to me before where I seriously wanted to learn the history and background of building this console, the process that was followed, etc. but was simply not motivated to continue reading the book because of its flaws.
If you are used to reading more professional novels or magazine writing by mainstream writers, you may be frustrated by the common grammatical errors, editorial errors, proofreading mistakes, etc. that pop up in every chapter. They aren't a big deal and you know what he is trying to say but when you pay for a book (that isn't all that cheap, by the way) you expect more. At least I do.
In summary, since I am an IT professional and an avid Xbox and Xbox 360 gamer, I kind of forced my way through the book to learn. You have to take a different approach to reading it, kind of ignoring errors, focusing on the highlights and not trying to tie everything together seamlessly, very differently than you would likely read any other book. If you feel this story is worthwhile enough to put up with these flaws, go for it. Otherwise, you may be disappointed.
