I still have a machine with a 3.5in floppy drive, and I still use it regularly.
Admittedly for somewhat esoteric reasons.
It's the only PC I have left with a parallel printer port, necessary for a piece of hand-built data gathering hardware. Unfortunately that PC also has a broken IO subsystem, and no Ethernet, so the only sensible way of getting the data back off the machine again is via floppy.
Still it's a hobby isn't it
