To me, it's about moving in this direction. Apple shows no interest in doing the work in MacOS to go here, and it's puzzling. Microsoft has iterated and iterated on it until it's pretty good. Not perfect, but they've already moved through a lot of the pain of making touch work well, and they're not stopping. When Apple figures out in 2018 that they need to ship touch screen laptops, they'll be years behind in UX on them... it's not as if they'll get it right on their first try, either.
