I actually don't think reading the docs like a book is efficient. I would just forget what I read, especially for those long detailed documents. I think it's better for me to locate the specific topic in the doc when I need it. I've always used Google Play Books as my epub reader in my Android devices (since it came pre-loaded in my first device) and I thinks it's pretty sufficient. I also use Apple Books in my ipad well, because it was the default one. :D And it's enough for me too. What features do you need? Why do you think these apps are limited?

Agreed. A lot of the documentation is stuff I wouldn’t use in my day-to-day. It may be interesting to learn, but it’s ultimately a waste of time if you’re not going to apply it. As you said, it’s better to investigate solutions to current issues.

When I do read them like a book, it’s usually on my iPad in Safari.

I guess I was hoping for something that would work offline like my kindle and also equally responsive. The epub readers I use seem very slow...however, I'm starting to wonder if the slow is related to the size of most documentation.
