I watched the Phil Spector movie on HBO Sunday night (it was terrible by the way) and in one scene a lawyer is talking about how a jury wont care about his success as a producer from so many years ago. To demonstrate this she pulls out an old 45 and an adapter to allow it to play on a turn table using a different speed. She asks a young lawyer what he thinks it is and the response is that it is an old computer disk. My oldest daughter asked me if we had color when I was a kid. I said sure, color film has been around for many years. No, did we see in color? she asked. Now that was funny.

C: is the default because it was assumed that floppy drives would take A and B and I recall early digital cameras that used floppy disks for storage. I don't have any of the devices I mentioned in my prior post and so far life has been just fine without them. Soon enough optical media will be added to that list.
