It depends if you have 3rd party drivers to install or not you will need a floppy. Personaly for $3-5 it is not a deal breaker and I would go ahead and get one. I have thoght of removing mine, but every once and a while I find I suddenly need to use it for something or someone. Keep it around for another 5 years and by then It might be gone.
One of my latest uses for the floppy is slipstreeming windows cd's and copying old floppy games to cd-roms to add to my archival collection of vintage software.
PS Although it is not installed, I still have an old 5.25 floppy drive, because old games and intesting stuff can be found at goodwill for cheap, Like a whole box of old games for $1.
