The electric outdoor barbecue sure didn't become a thing, turns out that people prefer meat cooked over gas or coals...
also the electric oven that will cook appetizers in 6 seconds? I think an overly optimistic idea of how powerful a consumer microwave could be.
The kitchen island with built in slide out fridge/freezer definitely did become a thing in higher end real estate.
also, I want that Eames chair from the living room. But maybe not with the white leather...
