Why does there need to be a LOT of change in e-readers?
Scrolls were used for centuries.
The differences was the content.
Bound books MOS (more of the same). What improved was mostly at the publishing end. Faster printing, color plates, faster binding, Printed covers. More uniform sizing (made Librarians happier
), all reducing production costs.
The differences was the content, production and distribution
Then e-reading arrived. Devices were huge (desktop), then things improved down to hand held, then better screens for text, Better battery life (something the old ways did not use), then color. And lastly, cheaper manufacturing.
The difference was again the content, and production paths. that could bypass centralized editing and printing.
Do we really need ultra high DPI? Those Ink Printed images were half-toned to avoid ink globs on mass produced books. Paper/velum had texture that affected resolution. I see little visual (text quality) difference between my first Astak and my current Kobo. Sure, I now have a lit page, a
little less weight and storage for more books than I can read in a month without a trip to my Library (be it B&M or my desktop PC).
