Yup. Try drawing a diagram and arrows with lines beginning and ending exactly where you want it intuitively with your finger. Not too mention you don't need to unlock your phone, navigate to an app to do it. Just pop out your pen and go. No need to keep anyone waiting if you're in the middle of discussing something.

Also one of the reasons I was looking to get a fold because the screen real estate was lacking. But they took away pen support in 7 so what the heck.
