This person, sitting right across from me, was glued to his Kindle for the duration of my 40 minute commute. There were roughly 50 people in the train car in which we were sitting. That represents 2.0% penetration, and my guess is there was at least one other Kindle – putting that number at close to 4.0% – on the train (what are the odds that the only Kindle was right next to me).
