Okay this doesn’t really serve a double purpose, but it’s just so cool I had to include it. My husband sent me a link last week to this CNet.com post on keychain devices. Most of us carry these convenient little flash drives when we travel these days. The trouble is how to disguise them from people looking to steal your data. Why not camouflage them as actual keys and put them on your key ring? They look more professional, less conspicuous and it sure beats the sushi flash drive!
