Olympus OM-1. Love this. The viewfinder is huge and the build is impossibly solid. It just feels "right" too; the shutter speed ring around the mount is clever as hell. Used occasionally.
Olympus Trip 35. Sharp 40/2.8 lens, meters without batteries, tough as bricks. I have a roll of 10 year old expired ISO 400 film in it right now, we'll see what (if anything) comes out of that
Nikon CoolPix 7600. My first digital. I have to give it credit for getting me interested in photography, but it's a very boring camera -- no manual control at all. At least it's small. Never use it now
Konica Big Mini something-or-other. Some sort of film P&S with a 35-70 zoom lens (
the flexibility!) that I used when I was a kid. I just found it in a box of stuff I haven't touched in years and was amazed to see that the battery still works! Don't think I will ever use this again, but it is a camera and I do own it, so...
