When did any of the ppruners last use this medium and what were the positive/negatives ?
Floppy disks are an inherently unreliable medium, not to mention their distinct lack of useful capacity and the fact that they are incredibly slow.
They have no place in todays home IT environment. Tape still lives on in business, but floppies are long gone.
With the advent of cheap USB sticks and hard drives (internal and external), and even cheaper CDs there's no reason to use them anymore.
