Besides SATA and SCSI drivers, there's really no need any more for the floppies now that we have flash drives and CDRWs.
If something goes seriously wonrg wth a system and I need to copy some data off of a computer that refuses to boot to Windows because of a virus/driver issue I usually go in with a Knoppix CD to rescue the critical data (try burning a CD of that data with a boot floppy).
And after seeing half of my 3ds MAX class back in college lose their classwork due to various Zip drive issues over the course of the semester while I never had any problems with my CDRWs and Direct CD, I really don't trust Zip drives much farther than I can throw them. They are just way too easy to screw up, and also too expensive and slow to do multiple backup copies like you can with CDs. Good riddance to magnetic media altogether, I say. I just wonder who the heck buys those Zip 750 drives, when you can do much bigger backups almost as fast with a DVD+RW and some good packet writing software.
