n-Tegrity (Score 1)

A much safer and better (and more functioning solution in the corporate environment) is the http://www.n-trance.biz/products/biometrics/bufd.h tmln-Tegrity device from http://www.n-trance.biz/n-Trance Security. Not only it supports very strong (AES256) encryption, it also uses your fingerprint instead of a password, so it's much more convinient. And (suprisingly) the fingerprint sensor works really well. I use one every day.
