Surf the net in privacy

Ever had one of those moments when you were using a public computer but wanted to access something secure online (such as online banking), and not wanting any traces being left on the machine? Well this product seems to help out in that area:

Stealth Surfer II: Protecting your Privacy Anywhere

From the article:

Encased in a common USB flash key drive, you’ll find an incredibly small and password protected application. The application launches as soon as your plug the USB flash key in and removes ALL (YES, ALL) traces of your acts. The reason is because the application stores all web and email data and cookies right on the USB key itself. It comes with the latest versions of Mozilla Firefox, for web browsing, Mozilla Thunderbird for email, Roboform for password management and Anonymizer for computer anonymity while you surf and do personal work online and on company time.

The idea is good, but starting at US$99.95 for the 128MB version, I personally think it is a bit expensive. But I guess you can ask yourself: “how much would I pay for my privacy?”
