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.
