What's the proof of concept with high res screens, they've been around for some time, just not in any consumer products. I saw some 1280*1024 2" screens several years ago. From texas instruments, i think its main use was in projectors, i don't know if it could have been used for displays but from the demo it looked exatly as an lcd but semi-transparent. 6" sounds pretty optimal for e-books i would say. ipad is too big and smartphones are too small. This is also where there is good reason to have such high res.
