Are they? Perhaps I'm out of touch with the brick and mortar experience. The majority of microwaves I've seen at my local department store are in a box, those few models that are on display are not powered. Even in the highly unusual case that they were powered or within proximity of a free power socket, I think it'd be rather unorthodox to go to the store and test drive a microwave with your instant ramen.
