I bought my first 35mm camera, a Nikon F with the plain pentaprism, when I was stationed in the Army in Turkey. It was purchased with a "never-ready" case. Subsequently on my next two-year duty assignment in Japan the camera came with me in its eveready case on many trips around the southern island (Kyushu), as well as Honshu (the main Japanese island) and Shikoku. I had a motorcycle and took many trips with my Nikon F carried in its eveready case.
That case was very well suited to my use at the time. I didn't have any accessory lens, just the 50mm f/1.4 Nikkor lens, and there was no need to carry a shoulder bag. The eveready case protected my camera from dust and other weather conditions quite well. The front part of these cases can be detached from the base, which avoids the "dangly" aspect in actual use.
I think it's fashionable to dismiss those cases as "never-ready", but they definitely could serve a purpose and were widely used by other manufacturers, including Leica, etc.
