Some n=1 anecdata: My circa-2002 Mr. Coffee brand drip coffee marker has an automatic cut-off. I have never bothered measuring it precisely, but I think it cuts off at around an hour and a half or two hours after being turned on. Believe me, there have been many times I put on a pot of coffee, got "in the zone" working on some code, got up a while later, walked in the kitchen, and found the pot of coffee stone cold. Much to my dismay. Although as a former firefighter, I do understand the intent behind this, and I can't really be mad about it.
