Actually, I think CD-ROM deserves a nomination.
It's an optical floppy
/without/ any protection from outside forces whatsoever. It's actually quite
horrible. It's also a read-only memory. Granted, there are burners trickling
down the market now, ten years after the introduction of the medium, but to
write anything to a CD, you have to go through an intricate mastering process.
At least cassettes usually had a simple user interface.
Sniff, its always sad to hear about life in non mac places. With the Mac
and even my OLD Sony I could drag and drop files just like with a floppy,
except of course files like music tracks from other CDs are automatically
accomodated. The burn command is explicit as it must be, but the rest is
fairly transparent using Toast. Creating a production master of an audio CD
from raw sound files is a bit more complicated, but
just about anything
else could have all the instructions on a single sheet of
paper.
Robust 650 MB of storage on media cheap as floppies, I need more punishment
like that.
