I came from an Air 2 with a tempered glass protector to the 10.5" Pro with no protector. I can't keep the Pro screen clean. As soon as I start using it, I see smudges on the screen. It also seems like particles in the air adhere to it more. Has anyone else noticed this? I heard on a podcast that it was because of a coating they applied for the Pencil. I'm not sure if that's true or not. It's really annoying.
