They absolutely do! I write floppies fairly often for some 90s era music sequencers and drum machines.

Music equipment is why I still have floppy drives, as well.

My Yamaha PSR-700 series workstation keyboard uses floppies as its primary memory, and still works fine.

Its replacement, Yamaha PSR-SX700, is coming out in October 2019 at MSRP of $1,999, and is not fundamentally different. (And if I use the 90s version to control Korg Monlogue / Deepmind / etc to get the sounds, then the marginal value of the new instrument goes way down).

So floppies it is.

There are floppy emulators that look electrically like a floppy but take USB or SD memory. Eventually I'll swap in one of these.

And PC's would still have floppy disk drives and RS232 ports if it wasn't for Steve Jobs :)

You say it as if having them were a bad thing.

The fact is, people who want floppy drives in their PCs can still install them. And RS232 is alive and well on Raspberry Pi.

On the other hand, the mobile world is suffering a lot from the "removing ports is a good thing" stupidity. That's how you get cell phones without a headphone jack, and laptops without a (micro)SD card slot and no USB-A ports (even when the space clearly permits them).

The ports that aren't used disappear gradually without the need to be "brave" (e.g. DVD bays from laptops).

*Serial is still alive and well on raspberry pi and other embedded devices; rs232 is a more specific protocol which defines voltage levels (higher than the 3V of the RPI), flow control, line length etc.

Well, Firewire probably would have won if it weren't for Steve Jobs too.
