Query: Beware the Kindle version!

I was so excited to get this book on my Kindle until I discovered that the page numbers are not available. When you are in a class and everybody is instructed to turn to a certain page - you will be out of luck. What's worse? No page numbers for the index?!?! How awful! Over 1400 pages and you cannot find your way around easily.This wonderful book needs to be fully enjoyed in the hard-cover edition...
