I'm with all of those who absolutely despise the overuse of them, with people babbling incessantly in public. I have one, have since 1985 (I kid you not, but those were "bag" phones for car use mainly). I sat on a streetcorner coffee shop on spring day, and watched cars turn the corner in front of me. I counted 57 out of 75 cars with people holding the phone in their hand, babbling away while driving. In Philly, you can see cops, meter maids, cab drivers - you name it - babbling away while on the job.
My biggest mystery? What do all those people have to say to each other? It's the equivalent of those 2-hour calls we used to have as teenagers, I guess, talking for the sake of talking.
I do use one, of course, but my calls are mainly to ask what brand of cornflakes to get at the store, or texts sent from the poker table. Not much else.
Of course, my wife thinks the same thing about me posting on Head-Fi. But at least it's quiet. LOL.
Oh, but I do love special ring tones, which are fun. My general tone is Sinatra's Ring-a-Ding-Ding, and when my wife calls, Lyle Lovett's She's No Lady (she's my wife)."
When I call my wife, her phone rings the theme from "Curb Your Enthusiasm" (an American TV show on HBO about a husband who can do no right).
