I have been using this book for almost 2 months to teach myself Flash programming. I do think the book is very good at making things simple and easy to understand but sometimes it's "too easy." I think those that are learning flash programming are already going to have some experience with using computers, so some of the stuff that this book explains is unnecessary. Also, there are no source files so sometimes I would like to follow the directions in the book to do something but I don't have any basic source files to do any of the things the book describes...so I think this book is only good for introducing the program. I need to get another book that actually has a more "recipe" like structure so that I can follow along and do as the book instructs but with source files.
