I know it's quite long and dense, but it really is a fascinating read if you haven't read it already. And, if you've seen everything he's talking about already taking place around you, it's a pretty scary read as well... And, Google will be one of the evil-entities at the heart of this, I'm betting (plus, of course, Microsoft won't let it escape their fiendish claws)...
