The Times has a brief profile of the StealthSurfer II ID Protect, a USB device that stores surfing history and other online information to the device instead of your hard drive. It includes Anonymizer, for masking your IP address, and RoboForm, for blocking nefarious keystroke recorders.
The programs come loaded on a flash drive, available from the company's Web site in capacities from 256 megabytes ($99) to 2 gigabytes ($279). Plug the flash drive into a PC's USB port, and all files created when Web surfing are stored on the drive, not on the computer's hard disk.
Just the thing to allow government employees to use laptops over public Wi-Fi?
