I got rid of mine about four years ago and have no desire to replace it. The thing was more of a hindrance than a help when I had the damn thing anyway, and it cost me too much money. They're only there so people can walk down the street saying really profund things like "yeah, I'm walking down the street" to nobody at all. The only thing that separates cell-phone users from the certifiably insane is the assumption that someone is actually listening.

Personally, I'd like to see the cops given powers to confiscate them outright from people who talk on them while riding/driving. I know it's not terribly 'trendy' for people to just concentrate on what they are doing, but hey, life's tough.
