This is more of a coffee-table or curiosity book than an in-depth look at either the science or history of computers. I found some interest in it as a result of not having much background knowledge in the field but for anyone who does have more than a passing interest in computers it will probably be much to vauge and basic to hold much interest.
I read the 2013 publication but not much, if anything, seems to have been updated from the 2005 original and the book's age is starting to show. I noticed several things I would expect to be included in a history of computing that were missing, including mentions of touchscreen devices, "cloud" data storage, the rise of text messaging to a popular form of communication, and, in the chapter on video games, both the rise of mobile gaming and virtual reality gaming.
In terms of physical quality it is a well made book with high quality images, so if you could find it at a cheap price it might be a nice thing to, again, display as a curiosity or a trivia book.
