You're out the door, onto the freeway and sipping you morning brew when all of a sudden you realize something awful has happened. You've left your cell phone back home. What to do? An informal online poll from the American City Business Journals group - not to be confused with the Los Angeles Business Journal - found that 46 percent would go back home. As for laptops, 21 percent said they would go back, while blackberries (10 percent), PDA's (3 percent) and iPod/MP3 players (2 percent) trailed the pack. One respondent, clearly representing the minority said, "There is no emergency that can't wait until I get back to the office. I HATE what these gizmos do to my lifestyle and stress levels - and they turn my colleagues into rude, unfocused, bad-driving, idiots. Let's stop frying our brains with these extra radio waves and start focusing on doing one thing at a time, well."
