with the end of 3.5 disks and the rise of retro machines usage i do feel there is a place for some standard device that would fit in a 3.5" slot that would replace it. some sort of 'super floppy'. whether it writes to mini-sd, sd, compact flash or usb wouldn't matter much. just a way to easily transfer from modern compute to retro computer. something that will be around for the next 20 years.
