When my last android died in a freak accident all I had was a spare iPhone mini. I find simply not having a good screen size for reading has cut down on my usage by easily half. I suspect e-ink phone users probably have similar effective phone aversion.
iPhone text prediction constantly messing with me didn’t help either. I’m sure it’s tunable somewhere, I just don’t care anymore.
I also have a small iPhone, but have had the opposite experience; text looks great thanks to the quality and resolution of the display and I far prefer it to my laptop for reading, with the exception of PDFs (my iPad was great for those).
