I didn't add a power switch to my 3D printer for nearly three years. Wasn't that bad, I had it plugged into a power strip and would use the switch for that to turn the printer on and off.
I'm not sure my laptop's discrete GPU works anymore. which is fine for the away mission web browser machine it currently is, hell if I need to do graphical work or something I can ssh tunnel to my desktop.
I used an old Dell monitor with a column of dead pixels for a shockingly long time. Thing just had a line of red down it about 1/3 of the way from the right edge. Ghosting and other artifacts have started to show. I still use it as a backup-to-a-backup on an old machine but it is out of main desktop service now.
