„Moral of the story: You only learn where a product needs improvement through serious long-term use. Users gain that kind of experience, but reviewers and pundits generally do not. Their observations tend to be superficial. That’s why reviews written after a few days using a product often miss the mark. The real greatness or lack of greatness in a product doesn’t show up for a few weeks or months. Sometimes even longer.

This was a secret of mine, because most of my competitors not only didn’t listen to their users, but they didn’t even use their own products.“
