I have to laugh at some these posts. I also lived in a world without cell phones and I (and the rest of the world) did just fine. Turning off your phones at a concert is not a big deal at all.
The irony, despite my prior comments, I don't have an issue with turning my phone off and keeping it with me. I do have an issue with being locked away from it or have it taken away by someone you can't trust.
Yondr is a system which locks your phone in a pouch which you put in your pocket. It is not taken away from you.
You are still prevented access from it.
Yes, that is the purpose of the system.
Indeed. Pleas to "terrorism" and "think of the children" on a topic of simply unable to access your phone for a couple of hours.
HN has experienced a palpable drop in quality recently.
