Hello! Gadget Girl here!!
I love my flash drive!

It is a 4gig Flash Voyager by corsair. I still haven't found all the great uses for it, but it does get used alot. One of the things we use it most for here is to transfer files between operating systems. We do have all the computers networked, but sometimes my Mac is hard to find. So it is quicker to just load the files to the flash drive and take them to the PC and download them. We use this mostly for movies and music and sometimes for pictures.
There are a lot less portable apps for the Mac, but I do have Portable Firefox and Portable Abiword on it. Portable Firefox has all my favourite settings and bookmarks on it, so if I am away from my computer, I can still see things as I like them! Portable AbiWord is a very good open source word processor. It is quick and doesn't take up a huge footprint. I use it for quick word processing over Neo Office which is a much bigger and more involved program.
I also have some pictures on it to show off to friends and family with computers. Then if they would like copies of the pictures, they can just copy them from the flash drive!
I am looking forward to finding more uses for my wonderful flash drive!
