As much as "Buy more equipment" is an unfortunate answer, I've given up with native floppy drives in modern computers. I do sometimes use an intermediate machine as a bridge box, but mostly have it down to a few gadgets:
- A greaseweazle (FOSS, preassembled for $30ish) for reading and writing physical floppies.
- A gotek drive emulator flashed with FlashFloppy (open source firmware for a sub-$30 commercial device) for feeding images directly to machines that covers most things.
- A FloppyEmu ($130; expensive but delightful) for feeding images to Apple machines.
It's mostly a good solution, and the first $60 gets a lot of reach if you aren't into Apple stuff (which has always been a bit of an issue, even at the time).
I was so annoyed by the dialog-buttons-in-title-bar nonsense that I ended up replacing my system gtk3 package with gtk3-classic the first time I used gimp after the 3.0 upgrade. It fixes some other bizarre gnome-isms so GTK3 software is less-jarring under KDE (or ...anything not gnome).
