How many years earlier does that let you retire?
While I'm on my 4th trip out for the day I'll bet he's already back home watching TV.
Joking aside, I've definitely see the cost/hr add up by purchasing new things that still have bugs to work out. The price might be $500, but I'll spend another $700 of time working on issues. I'm fine being a few months late to the party so I can conserve time for more important things.
In the words of the characterized OP: "If it ain't broke, don't fix it"
I can't fucking wait to retire, and spend time doing what I actually want to instead of useless work.
