> And what is the cost of unplugging devices after every use? You really think your time is worth so much that taking 10 seconds extra for plugging/unplugging a device is worth even considering? > Not just replacing sockets or cables Never happened to me once in over 3 decades. Both sockets and cables usually have a longer lifespan than any of your appliances. > Are electronic components happy now with the constant power on/off cycles? Depends entirely on the design of the device and the components used. The notion stems from the olden days of analogue devices, which indeed often didn't like being power cycled. Turning appliances on and off twice a day, though, doesn't affect the lifespan in the slightest.
