I drink espresso as well. It takes 1/2 hour to warm up the machine after I turn it on. Having it turn on and be ready for me when I want to make a coffee saves 1/2 hour. Plus I have time-of-use billing for electricity so having it turn on early in the morning during off-peak hours saves money! It takes more energy to heat the thing up to operating temperature than it does to maintain that temperature all day.
