First off, this is a fantastic book. I used the 1st edition with TFS 2008. This new edition includes great content for the new, completely revamped, build workflow process in TFS 2010.
However, as a new Kindle user, when I went to purchase the second edition, I ended up with the wrong one. After returning it via the Amazon Kindle return process (which is pretty painless), I was able to get the correct version. I wish Amazon had a better way of classifying/naming their book versions. They should call the Kindle versions "Version 1" and Version 2" to coincide with the book versions. Instead, there is the regular Kindle version (which is the new one!) and the Kindle "November 11, 2009" edition. Hover your mouse cursor over the Kindle links to see which picture appears. If you want the newer edition, be sure to click on the Kindle link with a "2" appearing in the picture of the cover.
As with any IT books for the Kindle, watch for missing content. I've been seeing this problem with a lot of IT books from Amazon. Maybe we need to create a web site called MissingKindleContent.com or a way (unknown to me!) to report Kindle errors to Amazon so they can fix it.
So far, no problems with this book. Big thumbs up!
