Floppy disks were always terrible. Slow, unreliable, prone to failure at the worst possible time. A simple magnet could trash them beyond repair. A bit of water could render them unreadable. Leave it loose in your bag and it gets bent? The thing was toast.
In the dying days of the floppy disk, around the time Apple introduced the iMac with no floppy drive, they were already obsolete. 1.44MB could barely hold anything useful at that time, most people doing any serious exchange had already moved on to Zip drives because they held a more reasonable 100MB, or CD-R since you could burn six times more than that onto them. If you had tiny WordPerfect files then floppies were adequate, barely, but what kind of a market is that?
So long floppy. You won't be missed.
Of course with flash drives we can wait the short time it typically takes someone to copy the contents off to get it back. And since they can hold significantly more data, they are also far more reusable.
The death of the floppy didn't kill sneakernet, the rise of portable networked computing did.
I am, and I do. Floppies were ubiquitous, durable, reusable, and cheap enough to give away. There's no replacement today - flash drives are the closest thing but when was the last time someone handed you one with no expectation of getting it back? Or bought a box of 50?
Sneakernet became much less vibrant with the death of the floppy.
