As outlined in this Slashdot.org piece, Farewell To the Floppy Disk, which links to an original piece at the BBC PC World says farewell to floppy, the floppy disk is, finally, dying.

I actually can't remember the last time I used a floppy disk, but I can count it in years, not months. I haven't had a floppy drive on any of my machines for 5 years, possibly longer.

While they were great at the time - and I used to buy my floppies in the hundreds - they were horrendously unreliable, particularly if you used them regularly, and although for their age they held a reasonable amount of information, today I can get a memory stick the size of a fingernail that holds 1000 times that.
