What in the world? Yeah, I think I can understand why this continually breaks your configuration. If you disconnect one or more, it now wouldn't match what you set everything up to be, and you would have to go through reconfiguring everything again every single time you power off or power on any of them.
Well, that is another interesting one that may be counterintuitive. Computers will fail quicker when they are continually turned off and on like that. It's far more thermal cycling, as all of the metals, connections, solder joints, etc. heat up and cool down every single day instead of staying at relatively the same temperature. That heating and cooling expands and contracts the metals, which does cause extra stress.
That's the tradeoff with all of that. The on/off cycles are extra stress, but does save energy. So this becomes somewhat of a personal preference and analysis of when energy saving is significant enough to be worth it to keep turning it on and off versus how it's harder on the equipment. I would agree that switches and LED bulbs probably don't have much wear difference, so yeah, I wouldn't leave lights on for that either.
