I couldn’t agree more. I’m typing this on an iPhone 12, bought new 6 years ago. My phone still feels snappy. And it gets me through a whole day with 60%+ battery remaining. The only real complaint I have is that I only have the 64gb model. I need to delete things every time a software update comes out because of how bloated modern software has become. But the hardware is fantastic.

I have no idea how much ram my phone has. So long as apps run well, why would I care?

You're missing the important bit in the GP comment:

Memory didn't matter when iPhone 12 was released, but these days it determines which local LLMs you can run on device. That's the point of that comment.
