Query: Don't buy the Kindle Edition

Amazon, you should be ashamed! This is a wonderful, elegant book, it's the text for my 2012 fall course on graduate classical mechanics, and probably for many such courses worldwide. Most students could really use a Kindle edition--but this one's horrible! Practically illegible, the equations in particular. The beauty has been ruined. For $42, you can surely do better. I'd planned on getting the whole Landau Lifshitz series on Kindle, but not until you get your act together. Please, please fix this -- notice this book is fifty years old and still the best. It will be for a long time to come, so it's well worth redoing.
