I like to get a nice laptop and phone because I spend so much time on them. An iPhone is worth it for me, as I like a predictably good camera. Before I went iPhone, I had a Pixel 3a, and it took perfectly fine pictures. I just like the iPhone cameras more, although I’m starting to get a little jealous of the better zoom capabilities on some Samsung phone cameras I’ve seen recently. Lately I’ve been upgrading every two years, but every three would also be fine.
