Well, it's not really "old", but in my grandma's never-ending quest for an "easy to use" camera, she ended up buying one of those horrible
Kodak Disc cameras back in the early 80s. The pictures were terrible, which is not surprising, given the negatives were 10x8mm. But the
worst thing was that camera was designed in such a way that by holding it, one of grandma's fingers was
always in the picture. No joke: if my grandma took 1,000 pictures with that camera, her left index finger appeared in 950 of them!
As for me, I had no telling how many of those cheap plastic drugstore cameras (that always used some odd film format). I then moved up to an inexpensive 110 camera, then a Minolta SLR, which I still have (but haven't used in 20 years). My first digital was an awful HP camera that literally
ate AA batteries. Funny thing is I now own a Sony W800 P&S, and the old HP absolutely
spanks the Sony when it comes to "challenging" pictures. Yeah, the 20MP Sony takes much better pictures than the 4MP HP on a bright, sunny day... outside. The Sony is also much more compact and has a decent built-in battery that lasts for hours. But once you try taking pics at concerts, or inside dimly-lit cathedrals in France, the Sony fails miserably, while the HP took quite decent shots in such circumstances. I had good seats for an outdoor concert this summer. I was mostly interested in the second band, who went on when it was still full daylight outside. I brought the Sony camera and took almost 300 pictures. Every one of them suck - I was only able to find 3-4 that were good enough for Facebook. I also took some pictures with my $85 cell phone... which were uniformly much better than the Sony pics!
