My current iPad is an aging iPad 2 that will no longer even sync or download media. It's slow as molasses, and yet: it's my primary mobile computer. I do most of my work in my home office at an iMac (also aging, albeit more gracefully), but when I'm out and about teaching and meeting with students, the iPad is my go-to. I've recently had to start using my wife's very old iPad 1 to play films in class (since my iPad 2 fails to sync).
So, to make a long story short ?*too late! ? I would use the iPad Pro as my primary mobile computer for both my teaching and writing work. And I might even dust off my old penciling skills and get back to drawing comics again after a many-year absence.
