I do not regret buying this very useful aid to using InDesign CS5. Having never used the program before I found it more useful then Adobe's own classroom in a book, although it does have it's merits. The brilliant series of books are not meant to be extensive tomes of knowledge but are invaluable for beginners like me. It provided enough guidance to assist creation of a 70 page heavily illustrated interactive manual. I probably could have managed without the book but I hate to think how long it would have taken me. May be not one for advanced users but I think the book was indeed brilliant. Recommended.
