My husband and I had a conversation about this earlier today and I've seen a couple posts here and on other forums that support his point of view. I got him the 12.9 for our anniversary. He wanted it because he hoped that iOS 10 would unlock features that would be optimized for the ram, screen size, and overall power. He got me one a few months later before a used his incessantly and kind of hoped for the same thing. Having seen that iOS 10 has no optimization for the pro, do you now have 2nd thoughts about updgrading at the first generation?
