I still think tablets will rule. Phones are either way to small to have many words on the screen, or they try to be a mini tablet (phablet) and fail at both being a tablet and being portable. Even the 5" eInks failed to sell that many units. Sony and others tried them, but they were not as popular as 6" eInks. I think people read most when they sit and relax, in which case a tablet makes more sense to them as they lean back in their comfy chair to read. In that case, why use a tiny or medium screen. Why not use a 7" or greater screen that is more book size.
