Hmmm people put sensitive data on tiny, easy to lose things that you can plug in any system? *shudder*
I'll stick to having stuff stored on my own server, on my own property that I can access anywhere via ssh and other secure methods and if need be can copy to a different location.
My uses for USB flash drives:
- random bootable linux distro 1
- random bootable linux distro 2
- random bootable linux distro 3
Installers/etc... for stuff I might need to be using in an enviroment without good online connection,
err... random music/vids/etc....
