I've been in tech for 35+ years. I've built CPU architectures, I can write device drivers, I can layout an 8 layer PCB, I can design an RF power amplifier.
I like the iPhone because it is easier to use than Android. My iPhone 4 was perfect. I'd still be using it if they haven't deprecated the OS and the battery died.
I have exactly 6 non-apple Apps on my current phone.
I want FEWER features. Integrated it or hide it. Don't make me have to learn about a new button, or switch, or setting or some magical tweak to use the basic features. If enthusiasts want to sniff and twiddle every last setting, go for it: give them dozens of settings until they burst. Just bury those settings away from me, or better yet: have a pro-mode setting that fills the GUI with all these features.
I want something easy to use with as few knobs as possible, and the ability to factory reset every app in case I screw up and accidentally flip some esoteric setting.
All of my college buddies and age-equivalent work peers (mid/late 50s) feel exactly the same way.
