@amic I agree that they can be hard to use, but in my experience, it isn't hard to avoid if you don't want to use it. I wish more laptop & keyboard brands had it, even though I would rarely use it. (Old, ugly, outdated is a silly position to take.)
@lnxw48a1 I will admit that I have tiny hands, but I have never had issues with hitting it by accident while typing. The nub can also be removed, and while it does look a bit ugly having it missing it means you can't hit it by accident.
