I had to use my floppy drive exactly once in the 2.5 years I've had this computer.
See, it was a dark and stormy night... no wait, it was an average day. Cold, yes, but after all it was during the winter. It was a Friday. A Friday on which I had to do a physics lab. "Well, I'm sick of doing boring stuff, what can I do this time?" I wondered as I perused the list of possible experiments. One of them quickly caught my eye. "Ooooh, radioactivity!" I cried with glee. Finally, after all these years, I would be able to play with substances that emit alpha and beta radiation (gamma would have to wait). Specifically, the experiment was to determine the amount of radioactive dust in the air. So you pull a whole bunch of air through a filter, then stick it in front of a Geiger-Muller tube connected to a computer and let it counts the ticks. Not wanting to wait the few hours it was going to take to fill up the filter, I stole someone else's and ran to the computer.
Now this is where it gets interesting. The computer in question was a clunky old piece of work. A 486 by my estimate; just going from the "Turbo" button and the LED panel displaying "33" that adorned the front of the yellowing case. Oh well, it would work for my purposes. With everything set up, I started the counting and analysis program and looked at the instructions one more time. "For best results, collect data for at least 10 hours" it said. "Screw that" I thought, and hastily scribbled a sign saying "FOR THE LOVE OF GOD, IF YOU BRING ANYTHING RADIOACTIVE NEAR THIS COMPUTER I WILL KILL YOU IN YOUR SLEEP", before rushing out of the lab and back to my room to play another level of Far Cry.
Monday morning. I wake up at 9:00, groggy from the all-weekend video game binge (how do you get past that last level in the volcano caldera, anyways?). I threw on some clothes that I found laying on the floor and headed over to the lab to get my data before my first class. I located the computer and the thankfully undisturbed experiment. I stopped the data collection and looked at the initial graph (which took nearly 5 minutes to calculate). A perfect exponential decay. Awesome; I'll just grab this, make it look fancy, do a quick write-up and I'll be done. But hmm, how to get the data from this computer over to mine? The instructions (which were of a particularly old vintage themselves) suggested just printing it from there. I looked in the corner at the dusty dot-matrix printer that looked like it hadn't been used since the 1980's. No, that wouldn't do. I was about to pull out my thumb drive when I realized that the computer had no USB ports, and certainly wouldn't recognize a flash storage device even if it did. So could I simply e-mail the file to myself? That had been my fallback solution on many occasions, but no, this computer was not connected to the network. Bloody hell, just my luck to get the only standalone workstation on the entire campus.
Glancing at the front of the computer, I then noticed the small slot of the floppy drive. "Aha!" I said. Finally, Naturally I didn't have a floppy disk so I actually had to go to the bookstore and buy a ridiculously overpriced one ($1.00!!) from there. But it worked! After getting back to my room I blew the dust out of my floppy drive and stuck the disk in. It crunched and clicked, but finally opened DATA001.TXT, bringing up notepad with a list of 32,768 numbers. "Oh thank Christ, it even preserved the formatting," I sighed. Excel opened it with no problems, and I was in the end able to do my lab write-up complete with pretty graphs and mathematical analyses.
THE END
But no, other than that I've never used it so I'm voting that I don't use it.
