It is certainly not vaporware; I have had one of these in my hands:

The display quality is impressive; it looks just like paper with a
semi-reflective transparent plastic sheet over it. However 'turning
pages' is annoyingly slow.

I fail to see the relevance to either newsgroup.

You should be paying attention, the October issue of "Esquire"
magazine had an e-paper cover, though likely they are now all
long gone.

It is sufficiently cost effective and available that it was used
on the cover of Esquire magazine recently. Of course, that was
just a segmented display, not dot matrix, but it *was* the e-ink
technology.

Dot matrix e-ink displays are used in the Sony, Amazon, iLiad, and
other book readers, which are shipping in significant volumes.

Presumably for the same reason(s) that many vendors don't
publicize specs and prices. Try getting the data sheets and
pricing for the TI 1710 or 2420 OMAP chips some time.

It really exists, but in itself it isn't much use. You need to be able
to put an electric field across it, either as a set of segments (as per
a Motorola phone and the recent Esquire mag) or as a scanned pixel array
with an active backplane as used in e-Readers. It's not trivial to do a
one-off.

I wonder who that was, given that E-Ink is in Mass.
