"Interesting listening"
The author seemed really have deep knowledge about Google. But I can clearly see his bias on Google - he really likes Google. The narrator was perfect, he surely sounded interested in what the book is about and passionate. As far as you don't take it word for word from the author, this book is an excellent book to know better about what Google is and where it is going.
"It's an eye opener."
The book delivers a single important idea and delivers it well - get your business organized from day one and work on your business not in your business. Highly recommended.
