I wonder if smartphone addiction actually has more in common psychologically with sex addiction. Both seem to involve compulsive behaviors more than dependence on a substance.

Well perhaps. It's the repetitive tapping on the screen. Seemingly at lightspeed it seems.

I've seen smartphones turn functional people into morons. I don't have one and don't ever plan on it. If I want to use the internet, I'll use my computer. If I don't have my computer, it's probably not an appropriate place to use the internet.
