Actually, just this morning. I use floppies to move files from one computer to another, and between home and work. Sure, they're not good for much else. But if the iMac is truly intended to be a consumer machine for newbies typing letters and storing recipes, then it's hard to understand why Apple chose to leave out the floppy yet put in a fast Ethernet connection. First-time computer buyers rely on floppies, just as they like to print stuff out, because they haven't migrated entirely into a networked existence like the more enthusiastic early adopters of the Internet.
Novices trust physical objects.
So it's unfathomable that Apple built a machine for them and then left out the floppy disk drive and the serial port, making it awfully tough to hook up a printer to it. That's certainly a plus. This is still a personal computer, a Macintosh, and that means it has more than enough problems and bugs and glitches to go around. Power off the printer and the iMac. Disconnect the USB adapter from the iMac.
