I don't know what they're feeding the Microsoft iOS development team but I wish they'd give some of it to the Mac team too. I've been using Word's latest new feature that lets you annotate Microsoft Word documents on the iPad with the Apple Pencil. It feels super natural and makes a great deal of sense once you get the workflow down. I was going to write it up but Jeff Richardson covered it thoroughly today so I'm just going to point you over there.
At this point I'm beginning to wonder if it's inevitable that I'll be moving my Apple Pages template documents over to Word and just go all-in for Word. There's a sentence I never thought I'd write.
