Most of the stuff you highlight can be handled by a feature phone, though, except reading books. I use my 6-year-old Android, doesn't seem to crash or need to reboot unless the battery is on empty (and shocking the battery still works pretty well after 6 years - will go 12+ hours between charges). You don't need anything fancy - what you want is something stable.
I'm really struggling with what to get next - the screen on my phone has been cracked for a couple of years now, so I should probably replace it one of these days. But now it's all these damn giant phones that don't fit in my pockets, don't have replaceable batteries - what ever happened to cell phones getting smaller?
When someone sends me a text or an email, there's no "he said - she said" disputes over what was said. Try doing that with your home phone.
If you have that problem often enough to care, you need better friends, not a better phone!
