I think a smartphone with an eink screen would do well in this developing market. It would have longer battery life and would be readable in direct sunlight. I really want an eink smartphone, preferably with FFOS.

The problem I've noticed with e ink is refresh rate. Dragging and scrolling look bad on some of the e ink device I've read about (android devices)

  The UI would have to be optimized to fit on one screen as much as possible. For example, the Kindle interface has paged interfaces more than scrolling interfaces. My biggest problem with it is trying to turn multiple pages. It takes too long, because it waits to refresh the display before you can load the next page. That probably has to do with the calculation of where each page begins and ends. I think that is calculated on-the-fly.

    The kindle looks good, until you open up the browser. You really don't want to browse the web on eink.

  There is a hack for the Nook e-reader that enables a fast refresh rate. Here's a before-and-after demonstration video on YouTube (four taps on the screen enable the fast refresh) http://www.youtube.com/watch?feature=player_embedded&v=6pBPsyno5PY http://www.youtube.com/watch?feature=player_embedded&v=6... Given that fast refresh rates are possible on e-ink screens, I wonder why e-readers don't have this feature enabled by default. Does it damage the device? Drain the battery? Or shorten the lifespan of the e-reader?

    Well it will obviously drain the battery, as e-ink displays only consume electricity on refresh. the 'ink' is either black or white, and changing the state is what costs electricity. Once the state is changed, it doesn't consume any more electricity. So increasing refresh-rate when scrolling increases the amount of current needed to flow through the system, and will indeed drain battery life.
