Simple Hack - Label Your Stuff

I have always put labels on my tech stuff. A simple label with my name and cell phone number adorns most of my traveling gear like my Mac, its power supply, a portable hard drive, and even my iPhone (of course using a different contact number). This would allow any person to easily contact me if my Mac ended up in their hands. I realize that if my stuff were to fall in the hands of someone dishonest, this really won't do much good but I'm an optimist and think most people would return lost equipment. It certainly can't hurt.
