Have you read it yet?
Over 1/2 way through and can't put it down. It reads a little like a novel and also like an interesting road map to the future of the Internet - which is obviously in the direction of cloud computing. It's something to enjoy on your next vacation or when you're relaxing somewhere. Very easy to consume and very well written and interesting - IMO.
I actually got it free after attending his webinar a few weeks ago. I downplayed it in my mind as a useless free book and was stunned by how good it was. Then realizing it's momentum to the top of reading lists I wanted to share my find with the Cache.
No, I wouldn't call it a real gear-spinner but I'd call it a clarifier.
