Good analogy, and you are probably correct, it doesn't happen.
I am not sure why people act like that on an iPhone forum, although this particular thread isn't as bad as many others that I have seen on the forum.
The comments stating that some people might have issues adjusting to a smaller phone after using a larger one is understand able. As someone that went form a 6s Plus to and SE, there was certain things I needed to adjust to.
But, comments I see all the time staying the SE is a toy or for children is just silly. There was one member on the forum that would post comments on just about every SE thread stating that the fans of SE must have tiny hands. Based off of the members name, I am pretty sure he was just using the SE threads as an opportunity to compensate for a small appendage of theirs.
No one knows for sure, but this same question was asked in a few threads a year ago and I said probably iOS 14 or 15.
Maybe iOS 13 might be the final one, or maybe it might go past iOS 15. No one really knows.
Yeah, it is nice, but since Apple discontinued the SE, those choices are diminishing.
Hopefully Apple will consider making a smaller phone in a future for the people that would rather not have phablet sized and priced phone.
