The world had mostly moved on from 3.5" floppy drives when apple dropped them, they were mostly used for windows boot disks and to transfer files between machines. Their complete hardware control allowed them to drop the former and their tiny market share meant they didn't have to care much about the later, floppy disks being incompatible between macs and PC's. The G# being a desktop machine also meant that for anyone that really did need a floppy drive an external one was an acceptable option, carting around dongles is not.

The world didn't care about wireless headphones until their wired option was taken away. It's a solution to a problem of their own making.
