Interesting news this. I don’t know that it will revive ereaders as a segment and I think we would be better pushing smartphone readers to simply use their current screens to read rather than making life more complicated for them, but:

YotaPhone’s makers managed to fit two devices inside one surprisingly lightweight handset. This is not just a Kindle strapped to a phone. The slim contours are even more remarkable considering the layers of protection needed prevent heat from the battery impairing the e-reader’s “ink”.

Once the basic instructions have been mastered, navigating YotaPhone becomes relatively easy – especially the central conceit of being able to” flip” content from the smartphone screen to the back e-reader.

News from the FT feed, for example, rolls down the electronic ink screen, making it easier to read and, crucially, consuming much less battery. Books and magazines can be flipped to the back to read.
