Certainly well documented and comprehensive. but precisely too much detail to get a real "breath" of the book. Above all, comes after Social Network on the development of Facebook and Steve Jobs of Apple. Hence the feeling to read again the same story of creation and growth. The character of Jeff Bezos is perhaps as interesting as that of two other entrepreneurs, but it vibrates less than the 2 other creators. A reading however for those who have not read the two books which I refer.
