I didn't make it through this book--as other reviewers say, it's somewhat technical. I just couldn't do it this time around, but it's very important information and I'd like to come back to it when I have more time to concentrate on it.
You know how you one time searched for something about a camera your friend had and now you're bombarded with ads as if you were Ansel Adams? Well, eventually that kind of stuff makes a difference... Honestly, I think I liked the NPR segment better than the book.
