Greg,
My first reaction is to agree with you. Your points are valid, however, I must now be honest with myself and look at my own situation. If you check my profile you will see that I have an Imation SuperDisk drive (as well as a zip drive and an external CD-R/RW.. Not to mention the Superdrive on my FP imac). I have not inserted a floppy into that Imation drive in over a year. it is just to easy to email small files to people. For back up, I use CD-Rs, my iPod, and I transfer files over the network to my 333 imac. I have also been known to put files on a compact flash card, and just carry the pocket sized reader along with it. No drivers are needed for the reader on any computer running OS X.. just plug it in.
In any event, there are still some uses for the floppy, but I think that at least in my case, most of them have been replaced with better technology.
Why do I keep the SuperDisk? Mostly for compatibility with PC friends that might happen to bring over something on a floppy. My father in law brought me an excel spreadsheet that he was having problems with on a foppy. I was able to mount it and deal with his problems. So until more PC manufacturers eliminate the Floppy drive, I suppose I will need to keep mine around. But, for my own purposes, the floppy is dead.
