I, like another reviewer, came across this book because it was mentioned in the New New Thing. I picked up and read the book because I've long been interested in Xerox PARC, and how it came to be. I was rewarded with an interesting, and seemingly thorough story about the people, motivations, and resources that came together at PARC.
I enjoyed the detail presented in the background material about the people and circumstances that came together to found PARC. There's a lot of good stuff about so many of the seminal minds and ideas that made much of the computing environment that we use today possible. I believe that most of the major breakthrough inventions that came out of PARC are written about, including the background, people, and stories surrounding them. If you are interested in the history of computing and invention, this is wonderful, fascinating stuff.
I expected more material about how and why Xerox missed so many opportunities to capitalize on the inventions created in this extroadinary place. To be fair, however, the story may be as simple as presented. The author also debunks the myth that Xerox didn't reap any reward from inventions that came out of PARC. But woven throughout the text and stories in this book is a case study about innovation within large companies, and how it is actively killed.
Again, I very much enjoyed this book. The stories that I knew little about before reading it are now much more clear. I found the stories fairly presented and free of jargon.
