I cannot say yet. I currently have a 10.5 inch iPad Pro and I’m a huge fan of the size in all contexts. I have never owned the 12.9 inch iPad, but feel like it would just be a bit clumsy and awkward. I am holding off until some of the real reviews come out, not just those from the major news outlets. While I am absolutely sure that the XDR display will bring improvements, I want to know if they are meaningful improvement in casual day today use, or if they are only truly noticeable when watching specific kinds of content.
