The format and tone of this book are geared for beginners, but it contains solid shortcuts and clean Lingo code that will benefit intermediate and advanced.
The Lingo section is clearly written and presents concepts in a well-planned sequence, but the type size and leading are so large that it's difficult to find specific information and there's relatively little actual content on each page. The authors provide powerful custom handlers but they don't differentiate them from built-in Lingo. Related Lingo appears on tables in appropriate sections, but it's usually necessary to get back into the reading stream in order to find the right code or syntax. The index references topics and subtopics, but no Lingo directly.
The book promotes poor design with its main tutorial project, an amateurish sci-fi scene with a badly designed user interface and 3D graphics that look dated already. If you're think about this for a course in professional interactive design, consider others.
Unlike other reviewers, I find that D7 Demystified is ultimately easier to use. It's easier to compartmentalize than D7 & Lingo Bible, and it's an excellent reference. This book does present better programming concepts, but its linear approach drastically reduces its usefulness.
