What's a cell phone???
Oh, one of these new fangled gadgets. Didn't have them back....when.
I use to leave the house to get away from the phone. Took some badgering for me to start to carry one, which I sometimes forget. But that's just me.
I don't see banning them altogether, but as long as the privilege is not taken advantage of. Ring tones drives me nuts anyway so I can see about having them on vibrate or off and do like Kaisu does. And definitely no texting on duty, IMHO period. If you can't keep your mind on driving or pt. care, then you don't need to be on duty.
