BIG difference between using it for a minute in a store to check exact needs with wife, and sitting in a restaurant, chatting all during the meal and disturbing folks 3 ft away. And WAY different from using it in a moving vehicle.

I have one...use it 'maybe' 30 minutes a month, precisely to do things like clarify shopping lists with wife when the store is out of something, or give somone an update about when I'm arriving on a trip. (I do wait until I'm stopped to make a call!)
