I'd say no... what will you use one for that you cannot now do with a CD? A Computer will Boot from a CD or DVD if it had problems, it will Install the OS with a CD or DVD, you can transfer Data with a CD or DVD. Short of you having a Boot Disc that is Dual Layered and isn't supported in DOS you'll be fine without a Floppy Disc. And even then! If you need 8.5Gigs of Space for something, a Floppy Disc won't help you :P
