I forget what post made me think of this, but I think a hinged two page e-ink device would be amazing.
I found a picture of this horrid looking hybrid device (the ShuBook by 1 Cross). However, the outer casing does NOT look horrid to me!

If that kind of casing was on a dual e-ink display device, I think it would be awesome. It would "shut" like a laptop or any other clamshell device to protect both screens when you weren't reading it.
Then I saw more pictures of another "concept" device that never existed that on the inside looks great with the two screens. The outside is so-so. I don't like the page turning/sliding.

Finally, saw an article about a dual screen eReader by PlasticLogic from fairly recently. However, it is a larger page size and is just a display with no storage.

I think a 6" reader with two touch e-ink screens (+ Glo?) and the "book" outside casing would be great. You could even "skin" the outside to your preference. As for weight, I'm curious how much two Kindle/Nook/Reader/Kobo sized devices stacked together would weigh compared to a regular reader with the attached covers and lights (especially if there was less hardware involved with the cover/left screen). The extra thickness might also allow for more battery power. However, I'm aware that making anything have more moving parts (hinge) can be a bad idea with electronics.
There
has been discussion about these types of devices before and I understand what everyone is saying about moving away from books, weight, etc. But I can't help thinking it would be a neat ereader!
2010 seemed to be the year when these concepts were being explored. PlasticLogic seems to be the only article I could find about something more recent.
