Resolution too low to call it 'paper'... (Score 1)

Considering low print quality is about 85 lpi (~170 dpi), average print quality is around 150 lpi (~300 dpi) and high quality is about 200 lpi to 300 lpi, I don't think this technology is ready enough for quality display since it corresponds to about only 50 lpi...

200 dpi would be, in my opinion, a bare minimum. I would qualify this a very nice start and I could see applications in things that don't require much quality: posters, restaurant menus, etc.
