MartinK said about Onyx Boox M92, that is hackable.


Although an e-reader can read pdf files, the reading it is not so comfort as on .epub files. The pdf was designed to deliver the document in the exact aspect as was created (same fonts, size, margins, etc). That exacteness doesn't fit well on 6", 5" screens.
In the other hand, epup is designed precisely to do that. So you can choose the size, font, interlined, etc acording to your preference and your e-reader device. Even the build-in dictionary works on epub files (not in pdf).
An EPUB file is a ZIP archive that contains, in effect, a website—including HTML files, images, CSS style sheets, and other assets. It also contains metadata.
