I used to have some friends who would use their phone when we hang, but they moved few years ago.
Now the people I hang out with either don't do it or some don't own cell phones/don't have data plan.
Just last night we were at a local bar and got to talking about some old movies and I was thinking to myself that it is like it was in the 90's or early 2000s - people tried to remember things instead of pulling a cell phone and looking it up. I wasn't even considering reaching for my phone. (Well at one point one person did, but he was a visitor from another state, not really a part of the group.)
I'm certainly happy to have my phone especially with LTE coverage in 99% of the places I go, but I don't feel I have to stay attached to it. It's there if I need it for something, but I am not running my life with it.
