Lovely writing! And I think the understanding that one can and should modify their tools to their needs is rather rare and should be appreciated.

When I had a MacBook, I was quickly compelled to do something about the fact that its sharp edges scraped things, most notably scraping off the surface of my fingernails.

But the obvious way to handle that problem is to put it in a case. For example: https://www.itslaut.com/products/crystal-x-case-for-macbook-...

I wasn't thrilled with a product design that required a case to protect the rest of the world from the product, but it obviously makes more sense than trying to file the MacBook yourself.
