If you’re concerned about keeping your data secure whilst on the move you might want to consider the Sandisk Cruzer Biometric USB Drive.
The Sandisk Cruzer uses fingerprint recognition to protect your data from prying eyes. In order to access the drive you need unlock it by a swipe of the finger (which you’ve previously programmed it to recognise). Very James Bond-ish.
You can get them on TG for $119.99.
