Using floppy driven Macs has some serious disadvantages:
- if you do it the wrong way you might end up swapping a disks a lot.
- you lack the disk space to put lots of (useless) gadgets in your system folder
- you lack the disk space to run large applications
- you lack the disk space to handle large files
- you can't maintain large folders, but are forced to divide the contents over several floppy disks

But there are also some interesting advantages:
- when your house is on fire, you only have to rescue a small box of floppys instead of dragging a complete computer out of the building. (with hard disk driven Macs this problem can be solved by daily backups on removable, easy to carry around media)
- suppose you have a floppy driven Mac both at home and in your office/pied-a-terre/weekend cottage, you only have to carry a small box of floppies with you to have the same setup and docs in all your homes and places (it is a bit like carrying a powerbook around, but only lighter and much less expensive
- the limited disk space urges you to be very economical and efficient, which may increase your productivity.
- you're less likely to suffer from hard disk problems
- you're less likely to get all your files infected at once when a virus attacks you, because they are not all on a single hard disk
- using floppy's instead of an external hard disk will keep your Mac Plus silent.
