I wouldn't call mine exactly useless, because I did get a couple of good years out of it. My first camera was a Ricoh that I got for college graduation and I used it for about 10 years before it was stolen. I was pretty broke at the time so I picked up a used T-60 because it was super cheap and came with a fairly nice 70-300 lens and I was able to pick up a couple of other lenses in pawn shops over the years. I got some good shots despite the horrible limitations of that camera. That was about 1992. A few years later, I had the scratch to upgrade my camera body only to be told "everything is EOS now, nothing works with your lenses." I think he offered me a trade in of five bucks a lens or something like that. So my tale of woe is more about obsolescence and bad timing rather than poor design, but it felt pretty useless at the time.
