This book was recommended by award-winning IT journalist Davey Winder, whose columns I have read for many years. It's very interesting but the writing was a little disappointing, it jumped around a lot in an attempt to keep things moving but just felt disjointed.
What bugged me most about the Kindle edition was the formatting. I imagine that the paper version includes footnotes within the text - the Kindle version does not. I got about 80% through and found the book ended and the remainder was made up of notes. Without much in the way of context, these were of minimal value.
Worse still was the index - it's just a list of entries without page numbers or hyperlinks. Completely useless.
