It seems Apple agrees with you on screen over the iPhone actually making/receiving calls and texts.
I am going to be critical of the PPI on the XR but in all honesty I am using an IPP 10.5 right now and the text looks fine. I have some tolerance for slightly lower resolution versus a screen that turns three different colors (not a joke.. my wife has the X) from in-hand to reading on a table/surface.
I agree with you PBz they surely could have done better with the resolution even at this price point, but Apple is greedy and profit driven. But like you I have a IPP 10.5 and I am satisfied with the text, so I think the XR would suit my needs just fine. That resolution deserves some criticism, but it doesn't mean I won't buy it.
