Query: A History Book about Computing

I recently finished reading the Soul of a New Machine which I really enjoyed and overall enjoy these types of history of computing types of books. This takes the next step forward from Soul as that was focused primarily on shipping out one machine this focus on three distinct different eras of computing, both the people who used and the machines.Overall I really enjoyed this book as an IT professional as it is the single best location of the history of computing. Other reviews go into much greater detail of the time periods and the technology so I wont repeat it here. I'm more echoing what others have said. If this book does sound interesting then I recommend you purchase it without hesitation. You will thoroughly enjoy it. I just wish there was more to it.
