And how did you handle this problem before the BlackBerry was invented?

Do you own a car, Mr. Luddite?

"Do you own a car, Mr. Luddite?"

Witty, indeed. I'll bet he does own a car. I'll bet he doesn't drive it in the theater, though.

Actually, portable cell phone jammers are in use (most probably illegally) already. Do a quick google, and plenty can be found.

In the SF Bay area it's a bit of a game for certain hacker types to go around causing calls to drop and watching people get upset.

Uh, apples and oranges? Cars don't go into theaters and they don't start without their owner's control.
