Hmm, I suppose a combo one would be good if it could automate the microwave-for-a-few-minutes-then-stick-it-in-the-oven approach to baked potatoes. Barakta occasionally fails at potation by turning the oven on, microwaving the spud, failing to set a visual reminder and then wandering off. Spud sits in the beeping microwave while the oven sits there using power.
