Do we read more deeply with physical books? That's one of the conclusions of this book, and I wasn't so convinced by it. I think reading on a mobile device, a tablet, or on a computer is totally different from reading using an e-reader with e-ink technology. The author discusses research that pointed out the importance of the "physicality" of books, the shape, the visual sense of how many pages there are in the book, and how all those cues are important for reading. There are interesting discussions on how technological native children will develop their reading skills. Are they going to be able to read long books? And get a deep understanding of the contents and ideas? Or the way they consume digital information will make them shallow readers? As an avid e-reader myself, I don't think there is a difference between reading a physical book and an e-book in terms of the level of understanding. The environment and distractions around me are a better indicator of how much I'm engaged in the reading. This book started a good discussion about the future of reading. And how our brains might change or adapt to different mediums.
