This book just fails to deliver. If you know anything about this area, you'll get nothing from this book. If you know nothing but are interested, you'll get an unrealistic view of where tech is going. The general direction and points that are made are generally where the tech world is going. However there are 2 big problems with this book. First, it's like reading a massive advert for a couple of products/services/companies (Google Glass being one). Second, the way technology is discussed is so out of touch with what it takes to actually invent and deliver such technology you don't get a realistic view of where the tech world is heading. As a professional working in this area I'm greatly disappointed by this by journalists who I considered to be knowledgeable. If you're interested in this area, you're far better off spending your time reading articles on the net than bothering with this book.
