On top of that, while there are e-ink screens that can refresh at 30Hz, they aren't bi-stable. In other words, you have to give up the main benefit of e-ink in order to get half the refresh rate of a normal LCD.
The fundamental problem behind e-ink refresh rates is that there's an inherent physical limit to how quickly you can shake your ink particles up and down without damaging things.
