Query: Not very helpful to me...

This book was a disappointment. Based on other reviews, I thought it would be the happy middle between a "nuts-and-bolts" type of book and a textbook with a lot of theoretical discussion. This book was neither, and weak in almost all respects.The book read somewhat like an undergraduate term paper, with overuse of "witty" commentary. Based on the large font size, large figures, lots of white space, and way too much extraneous commentary, this book is really much "thinner" than its 300+ pages suggest - not a good value.In short, there is not much meat here. I would advise looking elsewhere - compromises are often bad choices.
