I have seen the display in person at an LG booth at a show. I havent seen the Cover Story in person
But from everything I have seen or read iRiver has incorporated many of the things I like about other readers.
The compact design with the controls on the side as seen with the Irex, PocketBook 360 and Next Papyrus PageOne. The page flip bar from the Irex. The integrated cover of the PocketBook 360 .
Plus they offer the covers in other colors for personalization, its got auto rotate, wide format support including office formats, on board dictionary of course. And it has email functions
Plus pen input. Their "post it" method of making notes and connecting them to the text seems a good method.
