Query: another bad book from cisco press

Once again, cisco press has enlisted people who should not be writing books to write books. The authors, reviewers, and the editors have no clue what they are writing. I can tell they don't even know the subject well. They copied and pasted from the cisco's website and it has typos everywhere. Shame on the authors, reviewers, and the editors. Shame! Shame! Shame!
