Let's face it, flash drives are really convenient. However, if your flash drive falls into the wrong hands, so does your data. What's a paranoid geek to do?

Enter the Ironkey, sold by ThinkGeek. In addition to having up to 4gb of storage, it's encrypted on-the-fly with 128bit AES. When you stick the drive into a Windows computer, you have to enter the device password. If you fail the password entry 10 times, the crypto chip becomes permanently inoperative.

The Ironkey is also physically hardened against tampering. The insides of the flash drive are filled with epoxy, making it unlikely that someone could get in without damaging something. Exceeds US government standards for being waterproof. Sweet!
