> Yet very few people are making serious productivity apps for the iPad Pro.

Text entry is still an unpleasant process on iOS. Even with an external keyboard, not having a good way to move the cursor around the screen without touching the screen (and even then, fingers aren't precise enough to do this quickly) makes typing long documents on it painful. I love my 12.9" iPad Pro, but until they solve this problem, it's not going to be a good productivity device.
