Alternate use of CompactFlash cards

Leaving DebConf5, I went to Bratislava to join the ensemble on our concert trip. There, three people complained that they were having problems with their digital camera's storage media, so I started looking for a computer shop to buy my a flash media reader to be able to help these people out. As such, I now own a device that can read CompactFlash, Memory Stick, SD/MMC, and SmartMedia through USB2.0. As a Mass Storage thing.

What I don't have (anymore, at least) is a USB stick that I can use to store my GPG key on. The last one I did have broke down a few months ago, and I didn't buy myself a new one yet.

Since we have a stock of 32MB CF cards at the office (for use root filesystem in soekris devices which we sometimes sell), I took one of those, put it in the combined reader, and use that as my "USB stick". Seems to work. And is a bit more flexible, too.
