In the third world, an awful lot of times. But being an automated device, if doesn't deal with power outages, then I can't dependent on it to do cooking overnight, while I am asleep. Waking up and finding that machine didn't do its job, because power failed for a few minutes in the middle of the night, is not an ideal situation at all.
