apple was in the midst of transitioning to the kLine of consumer and pro hardware / software. During this time neither the iMac nor the powermacs came with floppy drives. More than likely Steve decided that since floppies were obsolete already. That being the case floppy support was more than likely never setup in the forts place. There is no reason for their new ultra modern operating system to support such obviously ancient technology. We all know hoe how his Steveness hates old tech.
