1-2-3 IS harder to do than 1-1-1.... of course only to a very very small degree. so small most people dont feel the difference.... but there is a difference. you need more movements with your hand, you need to think (even if its unconsciously) a little little bit more.

they streamlined many things over the years and while each of them make sense to streamline, if you look at the bigger picture it just makes it overall more boring. there abit of thinking less, and there a decision less and there two buttons less.
