I read this book with my iPhone handy and was able to find videos of many of the pianists he speaks of or to listen to the music he was learning. I would have loved the book anyway, but that made it even more pleasurable. I'm an adult beginner myself and his experiences were fascinating to me. It's a well-written, light-hearted book that anyone with a hankering to learn music in adulthood can relate to.
Editing in 2014 to add that after learning about Sonata Piano Camp in the book, I signed up to go last year. It's marvelous. Thanks to Noah Adams for writing this book since now I will be going every year :)
