I had wanted to get a physical copy from Amazon, but wasn’t willing to wait for months to get it. Then I checked the Kindle version again. When I looked at it a few days ago it was around $26 or so. Now: under $15!?! Well, that made it pretty easy for me to give in and buy it as an e-book, so I can at least start absorbing the information. Maybe someday I’ll still get a physical copy, if the book is as good as has been implied.
