Didn't Minolta actually have a model out that took cards? You want DOF preview, stick in some smarts? I remember rolling my eyes....

There's also a certain amount spent on stuff that looks like a good idea when you buy it, but somehow never really ends up being used. Many years (and a couple of kitchens) ago we bought a microwave oven that used magnetic cards to store cooking programs. You just picked the card you wanted, stuck it in the slot, and pushed "start". There was even a way to program your own cards. By the time we replaced it, some 15 years later, I don't think we'd ever used the capability. It was just easier to enter the time.
