Neither. Why would I sell? If it works just fine and the cost of ownership is low then I am keeping it. I don’t need new shit for the sake of having the latest and greatest.
I buy top of the line and use it until it breaks.
Then I buy a new one. I want cost of ownership to be low. My time is worth money, why do I want to waste it trying to sell it on Kijiji for top dollar?
Resale value is the last thing on my mind. Utility is first. Cost of ownership is a close second.
