I used to read a ton on my phone. When I warmed up my car in the morning, breaks at work, getting my oil changed, on a park bench. Very often when waiting for people, never for too long, but enough to get a few pages in and I don’t mind read-waiting. All the little snippets add up and all the sudden you’ve read a whole book! It started to really mess with my eyes so I’m an audiobook person now. But phone book reading is such a blessing.
