Right, I read them also. Unfortunately I think they aren't very good reasons and won't be purchasing the book because of that. I really loved the first book, easily the best django book I've read but I don't buy print books any longer for several reasons, storage space, environmental concerns, and price. I'm not angry about it but I'll not be supporting authors who won't provide the books in a format that is useful to me. It's far too useful for me to have all of my books available to me at a moments notice where ever I go. I work from a lot of different locations and it's far more practical to carry an ipad with me them a mountain of books.
