Kinda sad we never got a true replacement for/upgrade to the floppy disk.
I mean, there were LOTS of them, but no one true replacement.
In the 2000s, I was hoping that manufacturers would come together and create a standard form factor of usb thumb drive, so we could have actual usb thumb drive drives on our machines to pop thumb drives into and out of, but that never happened.
Of course, SD Cards and SD Micro cards fit the bill very nicely, but they never became general-purpose data storage devices, except for embedded applications like raspberry Pis (and of course, cameras and such).
Ah, I remember MMC cards! I don't recall if I ever used one myself, but they were popular in the earlyish "naughties."
And I do recall that funky mavica with the floppy->MMC adapter. ;)
I miss optical zoom. XD
