I know that nowadays it's not as important, but it's a little annoying. If the motherboard includes a floppy controller why should I buy a more expensive usb or floptical drive?
----------------
USB Memory, 8MB 16 euros
USB Memory, 64MB 29 euros
Floppydrive 10 euros
Disks 10pack 4 euros
Compare price and usability:
1) USB Memory.. plug'n'play, pretty fast and a joy to use.
2) Floppydisk.. screech craach, slow as hell, and probably broken in less than a month anyway

Your option would be... ofcourse... ?
