We decided to get a combination oven-microwave unit.
Silly question: Unlike a regular microwave, nothing in it rotates, right?
And: Do you also use microwaves to support each baking process?
In a oven-microwave, nothing rotates, but the contents heat evenly. I only use microwave-assisted combination baking for frozen pizza, and very rarely.
We have a micro + oven (compact) and a steam + oven (large). They are mounted on top of each other. For me, it's a very good solution. You can use the two ovens to make roasts and gratin, for example, or reheat meals, or bake dessert.
