I would never read books today if it wasn't for e-ink. I can adjust the font or the line spacing and at the end of the line I will read the correct next line instead of a 20% chance I will start at the same line.
I never had a big relationship to my phones simply because I can't stand typing on them. My plan (prepaid) is 1€/month for 1GB and 9cents per min/SMS.
I have a similar problem but my miss rate is closer to 5% so I empathize, I'm so glad you've found a good solution. truly nothing more inspiring in tech.
I think there's a lot of gains to be made in tailoring UX/UI to the individual. Not just for individuals (this person reading more books) but for societal advancement. (this person reading more books, generalized)
