> If the fridge was able to read this info and then you planned your meals for the week, it could tell you what you needed
I've seen comments like this in quite a few places... but does anyone actually pre-plan a week's worth of meals in any kind of detail?
And even the warnings about expiry dates don't seem all that useful. In my fridge, leftovers (rather than packaged products straight from the store) account for most of the stuff that's in danger of going bad. So the AC said, I'd have to tag them myself if I wanted warnings, which most people would probably be unlikely or unable to do. (How long does half of a tuna casserole last in the fridge? It depends...)
