I found on first reading this book, I was a little disappointed. I think I expected more depth from a series called 'The School of Life'. However, upon a second read of the book, I realised the power of the book is to act as a springboard to generate your own ideas and conclusions. As such, this is a great book. I found it to be an interesting (and quick) read that made me think about how much my digital world intrudes into my real world. My main take-out was to consider how much time I spend in front of shiny gadgets vs. time with friends and family, then take steps to redress the balance. As the publishers say, it won't give you all the answers, but it will stimulate you to form your own.
Overall, I would definitely recommend this book for three reasons; 1) it's a thought provoking read that invites you to reassess your relationship with the digital world 2) it is a quick and interesting read that is easy to dip into for reference or to generate new ideas and 3) it has numerous useful links to great websites to help make life easier and some very interesting further reading (particularly if you're a SciFi fan)
