First, I will state that I am a hands-on software development professional with thirty years' experience. So I have a little background on which to base my opinion. The style of this book makes it nearly impossible to produce answers to the practical questions that I have. The text dances all around any definitive answers, forcing the reader to intently analyze the information provided so that a practical solution can be formed. Clearly, the editor did not stop the author from continuing down the path of writing a book for those who are already quite familiar with applescript. If you are already an applescript programmer, this book might be of use. If you are attempting to learn by example and concept as I am, look elsewhere for explicit information. I will say that this book is an anomaly so far as O'Reilly books go as I generally find them to be quite excellent.
