This reminds me of something Bill Moggridge said in the industrial design documentary Objectified:

> I like the concept of wearing in rather than wearing out. You’d like to create something where the emotional relationship is more satisfying over time. You may not worry about it or think about it very much, and people don’t have to have a strong love relationship with their things, but they should grow a little more fond of them over time.

That was an idea he applied to the Grid Compass, which was an early laptop with a black-painted magnesium chassis, which you can imagine would patina quite nicely.
