Being in school, and having to deal with this crap, I say good smash the stupid thing.
Now before anyone says anything, I live and do business via my cell phone. But I have enough common courtesy to turn it off during class and meetings. If its a vital call that I have to take, its on vibrate and I leave the room. I would be embarrassed if my cell phone went off in class, I couldn't imagine picking it up. Personally its one of my pet peeves, drives me nuts in class to hear the stupid ring tones going off.
The student got what was coming to him, and I would have clapped.
