GoldKey Personal Security Key
This is a great gadget for anyone with personal files on their computer, aka everyone. With the rampant identity theft and security breaches that those computer nerds can take on nowadays, this is a great security tool to invest in. It acts as a key that when plugged into your computer's USB drive and opened with your password, unlocks all of your files with personal information in them. You can manage which files are locked/unlocked with it use, and it also recognizes them on its own. That way, no matter who gets their hands on your computer or hard-drive, they won't be able to access anything that could harm you down the road.
