Engadget points to a study showing that, worldwide, taxi passengers have lost 200,000 cellphones, 31,000 PDAs and 11,000 laptops in just the past six months. Oh, and 37 milk bottles, a pair of dentures and an artificial limb or two... The good news is that four out of five mobile phones and 19 out of every 20 computers found their way back to their original owners. Cabbies may be rude and may not have the greatest command of the English language, but they're honest -- especially in New York. Just two weeks ago, a Long Island cabbie returned $13,000 that he found in the back seat of his cab.
