Yes but not only that, for laptops it comes down to priorities. I know plenty of people who are better served with Chromebook with 8 hour battery life than a refurb high end one with 2 h battery.
> I believe that if a device was gently used and hasn't failed, the chance of it failing after 1-2 years is actually lower than with a new one. I don't know if it's true, but it's been my experience.
True for some devices and not true for others.

It's unhealthy to think about tools that way, off course rebuilding your tools increases their emotional value. If your rebuilds of tools are good, not very custom and things are not expensive, try to give them away to friends and family, it usually increases your satisfaction, lowers materialistic attachment and can make you more creative.
