I happen to really like 1980s semi automatic cameras and got spoiled by Nikon reliability- never got a dead one and never had one die
That's a good point. But seriously, when your livelihood depends on a camera working or not working, it's best to try to preempt disasters. Or if you pay good money to go on a trip and decide to bring only one camera - how does one make sure it'll work as well as possible? My latest trip to Iceland I had to really decide what to bring, and I brought only one newly serviced Hasselblad and two lenses with two backs. It worked very well, but I was still a little nervous.
Every single camera in my collection that I use for productive work has failed at some point. Hasselblad, Leica, Pentax, Minox, Rolleiflex, Holga, and ZeroImage pinhole (!). The first five are tremendously reliable cameras, and even though they have all been serviced, they failed at one point or another.
