Your boss not knowing how to type, John Madden refusing to get on planes — these are adorable quirks caused by being old, or phobic, or old and phobic. But a cell phone is so simple to use, so harmless, and so integral to how we’ve agreed to communicate as a society, that refusing to own one isn’t just the act of a Luddite. It’s a pretty serious power move.

Everyone has a cell phone now. There are more than 280 million mobile subscribers in America, according to the Federal Communications Commission. According to a 2005 international study by Advertising Age, 15 percent of Americans have interrupted sex to answer their phones. Even people who are videotaping themselves having sex, like Paris Hilton, stop to answer a call.

Not having a cell phone is a way of getting the world to run on your time. A lot of powerful people are already on to this. Warren Buffett doesn’t use one. Nor does Mikhail Prokhorov, the 45-year-old Russian billionaire who owns the New Jersey Nets. Tavis Smiley doesn’t own one, either.
