Sydney's Mom, thanks for bringing up this subject. Although I have entered contact details in "Personal Info" on the third screen of the Settings section on my Kindle, there have been a lot of other good ideas here that I'm going to consider in addition to that!
I hope some kind person returns your husband's lost Kindle. I was just reading at kindleboards forum that someone there was trying to find the owner of a Kindle that her sister found at an airport. (She didn't mention which airport.) They're sending the Kindle to Amazon since there's no owner identification on the device. So, there are good people out there! Amazon said they will find the owner and return it to them.
