As a developer living in Poland getting (original English) print books from O'reilly, Manning or others is expensive, plus this is unnecessary use of paper and space. Up until now I've been using iPad Air 2 (from 2015) for reading books and while it's OK, I desperately need to reduce my daily screen time. I think E Ink reader could help me with that. Features I am mostly looking for are:[*] good formating/display of code
[* ] support for Epub formats and non-DRM books is a huge* plus
[*  ] quick transition between pages
[*  ] not too heavy
