Thanks for Your suggestions. I am going to buy 11 Pro Max. I am wearing suits 99% of time. My XS Max fits well in my jacket pocket. And I realized, that if You don’t have iPad Pro, then bigger screen of iPhone makes the work more productive, than smaller one. And, of course, films, YouTube experience better on 6,5 screen. And I am well with one-handed use of my XS Max. It’s just time to make such experience.
