Worse, it gives you many more such things to misplace or get stolen. This CNN story discusses some of the retrieval services that help you keep what belongs to you. I particularly like the first one, about a new Singapore-based software that when you download it to your phone, messages everyone in your phone's database whenever a new chip with a new phone number is installed in the phone. This makes it very hard for someone to steal your phone as all your friends get their new phone number."
