As long as you don't have me on belay when that can't miss sales call comes through...
The point is not being missed. It's being argued against. One argument against is respect for others. I've been on a mountain top, enjoying the wilderness and the silence, when the sound of somebody's ringtone and the subsequent blah, blah, blah shatters all that. This 24/7 access is your choice, but please don't bring me along for that ride.
The OP probably didn't intend for this to become an argument about IF phones had a place in the wilderness. He seems to have decided that for him, they DO have a place. I also carry one, but try to restrict use to texting progress reports to concerned loved ones and emergencies.
