The wall street journal had an article about this a few days ago, with an excerpt. They chose the "human stories" for the excerpt rather than the technical stuff, but here it is for those who want to read it:
Edit: sorry, just realised this is an excerpt from a completely different book, "I'm Feeling Lucky: The Confessions of Google Employee Number 59" by Douglas Edwards, which has just been published.
But it may be of interest to people anyway (I hope!)
