I don’t even really watch movies on my iPad mini or 12.9 iPad Pro. Movies and shows must be watched on my big screen tv! That means I can only watch them at home of course, but that’s perfectly fine with me, since I prefer not to consume media when I’m out and about anyway. Except of course if I’m on a long plane ride, I’ll watch on my iPP. And if I want some side entertainment while I’m doing another task (away from my tv), then I’ll play something that either I’ve seen before or that is very talky/non-cinematic on whatever is the biggest screen handy, but for me that’s always going to be at work or home where I’ll have bigger options than a phone (iPad, Mac, or tv).
