well here is my experience....i havent had to share anything with a pc in a long time...and if i do, at college, your on broadband for the most part... just shoot someone an attachment through email...and if its beyond 1.44mb, its too big for email, and its too big for a floppy....at college, i have a zip drive...which is surprisingly the same price as a floppy drive... usb floppy drives are expencive (or were) so getting a zip drive that can hold 100 or 250 mb is better for the most part....
things i use to transfer files:
-email
-zip disk
-usb jump drive (those little key chain drives)
-external HD
-burned cd
-burned dvd
-ipod in firewire mode
-over the network (wireless airport direct conneted between my ibook and g5)
my recomendations would be, if you are really worried about it, pick up a usb zip drive... if you arent too worried about it, go to college and spend a month there or so before you decide to get something....
but i havent used a floppy drive in about 3 or 4 years...on my pc, i have it disabled on start up anyway...even pc doesnt use floppy much anymore
