I think I can get used to the siE of the X as it’s not much bigger physically than the 8 (ideally I’d still like the size of my SE but that’s not going to happen)
The main plus point of the X is not the screen size but it’s that it’s OLED rather than the 8 and most probably the SE2 which will be LCD.
It looks like it’s only about £70 to get apple to replace the battery a year or two down the line.
Main thing that’s putting me off is contemplating spending £500 on s secondhand phone!! But that seems to be the way now with the technological advances.
But if the SE gets the guts of the 11 it might also get deep fusion for the camera which would be a big plus point.
