I purchased the Kindle edition to complement the DVD. It makes sense to have the written format as well as the video. The Kindle layout makes it very difficult to read the text and refer to the photographs. They are not necessarily together, and it is often confusing which text & photo go together, and to refer to the photo as you are reading. Even the picture captions are often displayed with the wrong picture (in a series of photos you often get the photo displayed with the caption from the preceding photo). I am very disappointed, and expect I will now buy the book.
