I am not sure what large rock needs to be dropped on people's heads before they start realizing that there are really no redeeming qualities to cell phone ringtones. I have yet to hear a top 40's tune come blaring out of someone's purse or coat at a convenient time. I go to college on Wednesday nights, and at least once per class, one of those obnoxiously loud ringtones goes blaring out while the owner scrambles franticly through their purse in an attempt to squelch it. (To add insult to injury, the owner then proceeds to take 10 steps away from the group and carry on a loud conversation which we get the pleasure of hearing).
Ringtones rarely seem to bring the owner anything but embarrassment. Why are they used?
