We just replaced the old 2008 model of a GE profile MW and Oven with this new model. The improvements are spectacular. The upper MW can also bake and broil and supports Convection cooking just like the lower oven. Our old one could not do that. They enlarged the turntable and also allows you to stack 2 items at the same time. The control panel has over 170 settings for various types of food and once you select what you want it sets everything to the proper setting to cook your food properly.
