This is the big thing. So many times we want to heat up some left-overs and that would turn soggy in a microwave, but heating up the oven to reheat a few square inches of food is a vast waste of energy.

These take up a lot of space, though. I think one of those double ovens, where one is only tall enough for one tray, would be ideal. Convection, of course, but I haven’t seen a built-in without a convection mode in years.
