Do I miss the read/write speed? No. Do I miss the capacity? No.
...But I sure DO miss storage media that makes a satisfying "Kachunk" when loaded, and could be forcefully ejected like a spent artillery casing.
I've seen a few projects that stuff a bunch of flash memory into a floppy for crazy storage capacity, which is pretty cool. Maintains that nostalgia and commands much more respect than one of those ridiculously tiny little USBs that's easy to lose! :p
