Mr. "I Keep Cell Phones Until They Croak"
Don't try to pry a working cell phone, no matter how dated, from his gnarled hands. This easily-spotted specimen's phone looks more like a modern cable-TV remote control. Beat-up Motorola (MOT) RAZRs, even StarTACs, are popular. Awkwardly bulging, rectangle front-pants pockets are also good indicators that you've encountered him in the wild. Chances are he already knows, but it couldn't hurt to inform him that you can get a brand new phone for free from most wireless carriers. Even the iPhone 3G is under $100 on contract...but that would go against his "principles."
