I read this on my Kindle (I guess I read everything on my Kindle these days), and I should point out two potential issues. First, there is text missing from the Kindle edition in half a dozen or so different places. I don't think I missed too much, but maybe I did, and it did interrupt the flow. Amazon is aware of this problem, but I haven't heard anything smacking of resolution on this topic from them.
The other issue is that the physical book has a DVD that comes with it. I'd be surprised if the DVD had more than what you find on the Web, but I don't know.
Go read Brain Rules now.
