Have you used your calculator for something that was not really math related?

I have used my HP48GX for a lot of non-math things. I used it quite extensively in high school to tinker, to learn programming, and to goof off. I have used it

• as a remote control: http://www.hpcalc.org/details/2314 Every classroom had a TV which we used for "morning news" (our students produced a morning news channel) to switch to "better" programming (or just turn it off).
• as an address/phone book: http://www.hpcalc.org/details/50 I kept a lot of friends' contact information on it.
• as a metronome when practicing on my guitar
• as an alarm clock and stopwatch
• as a pocket video game device (plenty of games for it)
• as a digital set of flash cards
