I think this isn't the complete story. If turning your computer on and off reduced its life expectancy by 50% and it normally lasts 10 years -- is anyone going to use a 5 year old computer?
If, on the other hand, your computer is drawing 100 watts an hour to operate and you turn it off for 12 hours each day, you are saving over 1.2 kilowatt/hours a day, or roughly half a megawatt/hour a year. At an average cost of 12 cents per kilowatt hour, you are saving around $60 a year on electricity.
