> But then if floppies are diskettes, what's the non-'ette' disk referring to
Fixed disks (which were also quite large at the time.) Floppies were removable disks, like cassettes; disk + cassette = diskettes, also disk + dimunitive -ette = diskette.
Yeah, it's probably relative, I've rarely used disks larger than the 8" floppies so would never call them diskettes, the 5 1/4" were commonly called that in my circles. In IBM circles of the time they'd have a different default scale.
Like I remember being surprised the first time I heard someone refer to AA batteries as the big kind.
