I used a floppy just over a week ago.
Was trying to make it bootable so I could clone a drive, turned out the floppy controller was actually slightly faulty so it wouldn't boot from a disk, but it would work once within Windows.
Prior to that, in the last few years I've used floppies in college a few months ago (Win98 boot disks, to install Windows 2000 from a caddy drive) and before that, in junior school when we each had a floppy with our name on it to save work on. That's, what, 7 years ago?
Now, all my work is saved on my USB flash drives and various hard disks.
