I have resisted smart phones from the time BlackBerry came out with an internet browser. I didn't want my work emails to be accessible all of the time! Stupid thing became a leash and we've never turned back as a society.

It's not making us more productive, but less productive! The value from smart phones are the free apps, which are all trying to take control of as much of your attention as possible. What does that mean for your job? Less productivity!
