> Mainly, I'm just pissed that they axed EPUB, but still do iBook and Kindle. That is implicitly supporting closed, proprietary formats (or embraced and extended formats) rather than open standards. We have already been there once.

Yes, exactly, that was my reason for asking to begin with.

But I can buy into their explanation that amazon/iapples are much more downloaded as the number of devices are probably a couple of magnitudes larger.

But still sad a project with "open" in it's name mainly seem to support proprietary formats.
