As I read "As We May Think" I found myself writing a ton in the margins. Everything he predicted or described brought up in me some sort of modern technology. When he wrote about the department store and the ability to combine the information from the object, the seller, and the consumer into one I thought immediately of bar codes and credit cards. The personal library he thought of is our modern day laptop (or even a desktop computer). If you have a laptop and an internet connection you have in your posession much of the printed literature from the last half of the 20th century and on.
