I found this book to be just too "cute". There was too much contrived classroom dialog and character development of the students. That was fine for the first chapter or two but after that it was way to much to wade through. The actual how too's were buried in the student questions and quote marks that made it unusable even as a reference. In the end all that was developed as a sample was a one screen app with a few check boxes. No flow control etc. Not a very realistic sample.
