I am the very happy user of a Lexar secure Jump Drive. I love not having to carry a zip drive back and forth from work as I kept forgetting to put it in my backpack. (We can't access our office hard disks from home. 
The functionality was promised ages ago, was installed some time ago, but we are not allowed to use it.)
My first beef with the Lexar was that it was so small that I kept misplacing it, but a snap-release keychain from the hardware store fixed that, and now it lives in my pocket when not in use.
But I have a second problem: the thing is too fat for my Tripp-Lite ultra-mini USB hub The hub has two USB ports on each side, very close together, and the short ends of the rectanguar USB ports are almost touching. When I put in the Lexar, there's no room to put anything next to it.
