Dear Mike
As someone who "might" spend a little more time in the kitchen I can tell you that numerous kitchens have the microwave above the range top. In fact it's so common that the microwaves are often fitted with underhood lighting and an extractor fan. In any case when you boil something in the microwave it generates quite a lot of steam anyway, so I guess they are pretty well insulated against it. I happen to love them, definately something invented by someone who would use them.
Love Ann
