I have not yet purchased the newest update of this book, but was about to purchase it to read on my new Kindle when I realized that the edition for the Kindle is from 1994! That makes no sense to me, but I am glad that I caught it before I purchased. The low rating relates solely to the unavailability of a current version for the Kindle and the lack of a clear warning on Amazon's part regarding that.I would hope that Amazon will encourage the publisher to allow the latest version to be formatted and sold for the Kindle.
