Besides slow transfer speeds, I found that floppies were unreliable, since they only lasted so long.
I would often MEGA COMPRESS! my floppies to the extreme, tripling their size (to about 3MB).
This is awfully hard on a floppy, as you can imagine.
Then I got a 37MB flash drive. The speed alone made me forget floppies. Also, the 37MB flash drive worked with my Macintosh, so I could get updates on it.
