Thumbdrive Uses

[gfish]

I just got a free 256MB thumbdrive from work. I doubt I'll use it for transferring files much, since that is why we invented networks a couple decades back, but it seems like it could useful for copies of utilities and data I'd like to guarantee I always have available. I just loaded it with putty, pscp, a collection of favorite etexts and my PDFs of the Machinery's Handbook. What else should I add?
