however, since epub CAN be a source AND end format, it can ALSO be easily converted to other formats, if your device does not currently support it. for instance ETI (the makers of the eb1150) will support epub by providing a conversion tool that can accept it as a source format (the eb1150 can only read the .imp format natively), and mobipocket desktop reader will already convert epub to mobi format.
see the first post of this thread.
That means, of course, that in order to read on my Cybook - I have to download my books via the desktop reader - which is an extra step for me .
But none-the-less your argument is correctly persuasive, very laudable and hopefully will become a reality - but in what time-scale, who knows?, though I suspect there will remain obstacles.
