Kingston's Self-Destructing USB drive
The problem with USB keys is that if anyone gets their dirty hands on yours, they can have a look at the content of your drive without a sweat. If you are a security freak, then you'll like what Kingston came up with. This 4GB USB flash drive encrypts all data with 128-bit AES, and then adds an extra layer of security: a self destruct feature. If someone tries to enter a wrong password more then 25 times, the data on the drive goes bye bye!
