But none of what you described explains why you would need a Pro instead of the standard. Its nice to have, but the base model isnt nerfed to a point that makes it unusable.
1) They age better, and oftentimes are more not just useable, but actually a joy yo use, for a longer time
2) The price difference just isn't that much to justify taking a lower power device. Sure, the iPhone 11 would probably be just fine compared to an iPhone 11 Pro. But when you're talking about phones in that price caliber, honestly what's an extra $200? And I've never had a phone in my hand wishing it was less capable, so why chance wanting to replace it earlier?
Like I said, I bought the X at launch and that was to replace, in turn, a 6 Plus which was still very usable so I'm far from an every year upgrader, and I think that has to do with the fact that I always get the biggest and best, and then just age out a few cycles instead of continuously upgrading.
