Yes, these curved displays can be configured in almost any shape today, but only once. Then they have to be encapsulated in glass on the front and metal on the back to keep out moisture and oxygen, both of which degrade the screens in a short time. What dozens of companies worldwide are trying to develop is a flexible plastic that does not let oxygen or moisure slowly leak through. The company that invents this flexible ecapsuation technolog will be worth billions overnight.
Flexible screen technology will make screens compact for transport and also allow curved screens for a "total immersion" experience. Using existing technology, Samsung is already offering a 78" diagonal LED (slightly) curved Ultra HD TV screen (for a cool $9,000) which allows the entire wide screen to be perpendicular to the viewer at a suitable viewing angle. The new flexible screen technology, however, could be lightweight, much more immersive, adjustable depending upon the desired curve angle, and a lot more affordable.
For an electronic display, there seems little point in having more than one page, since the content can always be changed. I think I'd prefer a tabbed display; that would offer the option of reading straight through, or turning to a particular page immediately. Non-linear navigation's especially relevant to a newspaper.
Just don't waste effort and processor cycles making shuffling noises! Leafing through a "magazine" display that can only be negotiated sequentially, slowly, to the artificial sound of pages turning is madding, both directly and as an illustration of how to expend resources to render an interface unusable.
Here's an example: an archtect could overlay on top of a blueprint of a lot, then display differenet house designs and layouts--with the room, doors, windows and everything displayed with brightly colored lines, circles, whatever. Also the military has all sorts of uses for them to display tactical informaiton--from the war room to the visors of solders.
