I actually took a bit of a vacation last week (fairly unusual these days) and had a chance to do some reading. The timing was good as the book was just released.
All I can say is WOW. It took me a while to get through this sucker because it's just densely packed with ideas from the future. The book takes place in about 2050 or so when a lot of our technology that's ramping up now (like Augmented Reality) is simply a part of normal existence. It's simply page after page of Brin's astounding thoughts on what society could look like in the near future given current trends. And of course it has a larger theme but read the book before spoiling it.
I would highly recommend Brin to anyone who thinks about the future or who works in this kind of technology.
I also read "Red Shirts" by John Scalzi which is a fun easy red. It's about these guys on a starship who get all meta and realize that they are the red shirts and are going to die. Quite funny, especially if you get trek.
