Actually i would not mind a fridge with a built in RFID reader that can figure out its contents and dump me a list when i stand there wondering what to buy for the evening.
I don't know about everyone else but I don't always want the same things in my fridge other than a few standards like milk, eggs, butter. And I can see at a glance if I need those. Everything else I buy more on the basis of what I feel like eating that night or the next couple of days.
Yeah, I'm not that enthusiastic about it. But it brings up interesting things like a system showing recipe ideas you can make without going to the store or whatever. Which maybe that is stupid too, but there are lots of possibilities. So in some sense, the 'works great' up there has to include a compelling use case.
And you'd need the tags to be embarrassingly cheap. If you want your box of cereal to have an RFID tag, the RFID tag has to be a fraction of the price of a piece of cardboard.
