Good Book, Bad Kindle Edition
I just wanted to let other Kindle owners in the IT profession know that the content of this book is as good as the other reviews indicate, but you should buy the paper edition rather than the Kindle edition.
Most of the xml in the Kindle edition is unreadable, due to its being truncated at the left margin, and sometimes at the bottom of the page, as well. Some of the sidebar content has the same problem.
All in all, there's just too much content missing from the Kindle edition. With the hard copy being just ten dollars more, it's the better choice.
