This might be an unfair review of this book, because I'm not quite the intended audience. Right there on the back, under the publisher's mark, there is a "Book Level" category (boy, do we designers love to categorize!), and it clearly says: "Beginning/Intermediate".
Having already devoured books like Cradle to Cradle, Worldchanging, and Design Like You Give a Damn, all of which go into an enormous amount of inspiring depth about what designers actually are doing about the state of affairs today, this book came off as sort of old news. I have a hard time trying to single out anything I actually learned from it that I hadn't already read elsewhere.
BUT... for those designers who are new to the idea of ethical design practices, this book clearly and concisely presents some excellent and compelling arguments about our responsibilities as designers, and some very top-line basics of how we can change the way we do things.
The one thing I did get out of it was toward the end. Berman very persuasively argues (guilts you into...) taking real action now. That's something I can and should hear over and over again, regardless of all the facts, figures and role models I already know.
