What to do with small memory size USB Flash Drives

Today I found out an interesting article posted by Michael Kwan here that explains how to get benifit from existing USB Drives.

Here I will give the synopsis.

1. If you are using Windows Vista you can convert your USB drive to a Computer Lock. The process of doing this is explained here by Lifehacker.

2. There are versions of Linux that you can carry in the Thumb Drive. Visit http://www.pendrivelinux.com for the possibilities.

3. Again you can load portable Apps. This helps you when you go to internet cafe as suggested by Michael Kwan. You can find some USB portable Apps here(http://portableapps.com/). 

If you also have any more Ideas feel free to add them here.
