Floppy Disks Show more
And I come at this from a weird perspective.
Floppy disks were an anachronism even when I was in school. We still used them, because most everyone still had at least access to a computer with a floppy drive, but they were going the way of the dodo.
But the way we used floppy disks has never been replicated. USB drives are too physically small, and too expensive.
CDs are read only, or they're "read/write" but only barely, and they're slow!
