I found Nano an interesting read. As a book, it lacked a lot of the technical guts, and more importantly, a broad overview of the potential social issues involved. But although I found this a little dissapointing, I stand in defence of the author for the simple reason that the average person usually doesn't have the skill to read deep technical texts (a skill which is developed by a long interest and/or study in the area). As a primer to the extremely important concepts and issues concerning nanotechnology, I give it a thumbs up. He generally sticks to the realities of the technology, avoiding the inevitable sci-fi fan rubbish which can congeal around such concepts (look a space travel, after all). I can understand not going into the more social and political issues of such an emerging technology as it can scare people, but I still think he should have elaborated more in this area. People have enough trouble dealing with the technology of today, having them (even more) unprepared for future technologies can be extremely dangerous. The best read on Molecular Nanotechnology for the average reader would still remain 'Engines of Creation', by Dr. K Eric Drexler. The book is still value for money, regardless. I give it four stars.
