Not sure if it is atrocious but not having a back key in the OS is really a pain in the a... I have to learn how to go back from every single page every time a friend gives me an iPhone to perform some task. Everything else is more or less the same with every new software system: you have to discover how to do things and there is no easy way out of that. Example: I remember I had problems finding how to send SMS on an iPhone in 2012: the owner was driving and I had to answer one.

I have the exact opposite reaction. I find android lacking in many ways, even though i sorely miss killer apps, such as termux, and the general openess on ios.

Being a 90% linux vs 10% macos kind of guy, it feels a bit weird to promote the ios UX, but I guess it emphasizes the fact that people might be inconsistent in their likings, hence the need for choice.

I know how you feel.

Apple design their UX for majority. I worked on MacOS for a few weeks and it was nightmare. Like someone removed most of features that was useful to me and added a lot of garbage.
