Unfortunately,
ePub format support in 902 is POOR at this moment (last 2.0.4 firmware).
Technical books (e.g. purchased in O'Reilly online store), and not only technical books if they have formatting - can't be read on 902 (and on all devices with this firmware) if they are in
ePub.
Despite the fact that 2.0.4 firmware has TWO readers for ePub - AdobeViewer and fbreader:
AdobeViewer is totally useless for two reasons:
1. If the page is not fully filled with text (and in technical books it is at every step) - the time of going to next page is about one half minute! That is terrible, I can make a coffee waiting that will be done...
2. In AdobeViewer totally not works dictionary - it opens but can not select words and finally crashes (and I'm not a native English speaker, I need it).
Fbreader is useless twice: it just renders the pages with some text LOST. And do not formats the remaining text properly (must be centered text is to left of page).
That is the page of one of ePub books as it is seen in the windows reader application:
And this is the screenshot of PocketBook Pro 902 with this ePub opened in fbreader. You can see - the LOT of important text is lost:
So, I have 902, but I read the O'Reilly books on computer so far... (Do not offer PDF to me, format with not changable font size is format for paper of appropriate size, but not for electronic screens, it brokes my eyes)...
PS. Sorry my English. Sorry my opinion (for PDF-lovers).
