Interestingly, the Lenovo ThinkPad USB's housing more closely resembles a burglar-alarm panel. Pressing and holding numerical combinations allows you to change the password or modify other settings, without having to run software.
The Lenovo ThinkPad USB produces no sound when you press a key, which is a good thing, but it offers no visual feedback that you have pressed a key, either.
The Lenovo ThinkPad USB demands a lot of power to do its thing, so the box includes a second cable that you're supposed to plug into a second, free USB port and then feed into the drive's power port.
The Lenovo ThinkPad USB is platform agnostic, easy to use and good looking. But you do need two USB ports, and reprogramming the password can be difficult.
