I went by Costco today after work. They had the 11 Pro Max and 11 which closely represent the 2 screen sizes. I’ve had an X for 3 years. It feels small and prior to that I had 3 years of 6/7 Plus phones. The X has a more cramped keyboard which leads to more typing mistakes. I also use my phone for so much email and web, much more than a computer that it is my computer. For those reasons and definitely the better spaced keyboard I am going Pro Max.
The 11 was almost the same size as my X. Negligible difference. The Pro Max felt much better. Yes, unlike my 7 Plus which didn’t have full screen there is going to be more 2 handed and use of reachability and that will be a bit awkward, along with the pocket size, but I have done the larger body before.
When I got home I took my wife’s 8 Plus out of its case and put it in my pocket and felt the weight for a good idea of what the 12 Pro Max will be like.
