So, to read directly from a usb flash stick - it is still safer to have it at the top, not at the bottom. Cool Reader allows upside down orientation. The default reading app of Mimas/Alita/Ares - does not, it seems. But they all have cards anyway, so OTG workaround is not needed.
And Onyx Boox Note 2's default reading app allows 180° orientation - so everything is fine.

BTW, with a bluetooth keyboard, do I need some special app, or android > 4.0 handles everything so that Page Down / Page Up keys turn pages in every reading app?
And probably sound +- keys would work too, because they work on Mimas to turn pages.
