I think everyone (techies mainly) should buy U3 Flash Drives not for the launchpad itself, but for the autorun mechanism. After growing quite bored with the bulky u3 launchpad, i've explored the art of cd partition replacement. By doing this i have been able to:
Autorun a favorite app launcher
Autorun an encrypted volume
Here are the simple steps i've taken:
Now when i insert my flash drive, Rk Launcher starts up and i get a dialog box that asks for my volume's password. The truecrypt volume contains information-sensitive apps like: keepass, firefox portable, gaim, and sunbird. If my flash drive should ever get stolen, i'd feel safe knowing that my data is safe.
If you have any questions or comments, fire away!
