The credit card drive is a little expensive when you can pick up 1 GB drives from some office supply stores for $19.95. I would be afraid that it would get wet or snap, or if someone got my wallet they would have access to my files.

U3 drives me nuts. It won't let me eject my thumb drive without telling me its an error, pops up all the time when i am working, just a pain in the behind. I need to figure out how to get rid of it.
