I do have one of those Edison diamond disks in my collection, though no playback device that can handle the vertical signal in the groove. My ~1917 Silvertone phonograph does fine for me with the more conventional 78s.
My grandpa used to tell me that they donated the clockwork out of their record player as scrap metal for the war effort, so they listened to music by spinning the records by hand and holding a fingernail in the groove. That's something you can't do with pretty much any other recorded medium, aside from print.
