So what those people are probably saying amounts to: they are comfortable with what they have and don't want to learn something new...
...except that when Microsoft occasionally *forces* people to learn something new (e.g. when they released the ribbon UI for Office, or the crazy Metro UI for Windows), people swallow that pill anyway because they have to. What it really comes down to is that most people prefer living their lives in a catatonic/comatose state.
Diplomacy is the art of saying "nice doggy" until you can find a rock.
