But they still were alive (what a shame to retire something > that still works!) I don’t think John is saying that on the first day of the machine’s sixth year that thou shalt throw the machine away. Rather, be happy that it gave well over the 3-5 year use life you should have budgeted for from the start. Between the lower power draw of the replacement over its expected lifetime, the time taken to diagnose it, the parts required to fix it, and the time required to replace those parts, you’ve probably spent more than the cost of a new machine. That leaves out the increased productivity from running on a faster, more featureful machine.
