Story: Xkey USB drive allows remote access to Exchange email

"When the device is removed, it automatically deletes the contents of the computer's cache, leaving no trace of the user."

Ummm... Am I the only one here who saw a red flag when I read this? They say it's totally secure - but it stores all the contents in a cache on the computer you are using. What happens if there's a power outage before the cache is deleted? Who's to say that the computer doesn't have a program on it that doesn't allow you to delete the cache without super user priveleges.

In other words, this is no more secure that any other VPN program. That's all it is really: a VPN program put on a flash card connected to a USB connector.
