Flexible Electronic Paper
shri writes "E Ink has just announced a breakthrough in flexible electronic paper displays. The new display which has a 100DPI resolution and is only 300 microns thick has the potential of truely changing the way we read our information."
Considering that most of us are staring at a 96 DPI screen at the moment, I'd say that 100 DPI is pretty darn good for a digital screen. It's still behind paper, but not by too much. 150 DPI is excellent quality. Anything over that only increases sharpness and fidelity.
144dpi = dot matrix
This is somewhat misleading. Many dot matrix printers weren't able to produce dots without gaps, giving the paper a ridged appearance. As long as the pixels are flush on this display, you shouldn't have any problems.
According to this page, the paper retains the image when the power is removed. Even more info here (PDF).

The only new thing about today's press release is that it's bigger than before and higher resolution. But yesterday they announced a colour version, which is a bit more newsworthy.
