PCWorld.com - U3: Portable Programs on a USB Drive "Petite USB drives, already handy for carrying data, are getting smarter: New technology from a company called U3 allows a drive to store and, when plugged into any PC, securely run applications--without leaving a trace of data on the host computer. The applications (which must be U3-compliant), data, and personal settings all reside on the portable drive, permitting you to temporarily turn any Windows 2000 or XP system into a personal workstation without threat to your privacy."
