For the iPhone, I tried looking at the Pixel for the Vanilla Android experience and long support, yet it seems like people are fighting battery life issues all the time. Not to mention the polish of the software, app ecosystem and stability.
Also, couldn't find anything coming near the value of a baseline Macbook Air M1 as far as build quality, battery life, stability etc. is concerned.
I like to also read comics and magazines on the iPad and that's also a market where I have no idea what an alternative would be. And that's the state of the tablet market for years now.
Maybe I could get rid of my Apple Watch, but it just works and has endless amounts of third party accessories. I've been looking at Fossil Hybrid Smartwatches and it seems like they are a hot mess of instability and bad support.
At the end of the day, it's about stability and ease of use. I'm way past the time where I had the time and found it really cool to try every new ROM coming out ("daily driver", "What isn't working? You tell me") and it seems like Apple still can't be beat at this front. Sadly.
