Moore's Law, which suggests that processing power doubles at the same price point every 18 months, has held true since 1971, and it doesn't look like it's going to slow down anytime soon. We'll have plenty of uses for all that processing power. I realize that the traditional floppy disk is just about dead. The standard 1.44MB floppy disk just doesn't cut it for backing up data files of any size. It replaces your floppy disk drive because it also reads the same 1.44MB disks.
Many people have such drives, so they're fairly useful for file swapping.
