Anyone have experience with e-paper?

I'm designing a portable ebook reader/web browser, and I'd like to use
the new "e-paper" I've heard so much hype about. Does anyone have
experience with this stuff? What type of interface does it use? Is
there a good place to get small amounts of it? I saw one company that
sells an evaluation kit for $90, can I get just the paper itself? How
flexible is it? How fast does it change color? Are there any pitfalls
to it's use (besides it being monochrome)? If I mount a touch panel
over it, would it be damaged by stylus pressure? How many DPI?
I've searched and searched, but all I get is fluffy "e-ink is the wave
of the future!!!11!one!!" articles.

Thanks,
Mike Matthews
