People who are surprised about the time spent on mobile devices have obviously never been in a waiting room nor public transportation. Since the iPhone, people have had a chance to kill "dead time" which would otherwise have been spent staring into walls and windows. Twitter's microblogging and -communication, of course, has exacerbated this where we see celebrities who tweet when there is downtime on the set where they are shooting. I think it's completely ridiculous to say that this is something particular to mobile apps rather than mobile proper.
