I just summarized what I read elsewhere. I have never seen one in real life.
It does look good in the comparison you linked. It is being backlit though, while the E-ink is not. Maybe the mentioned blandness is more of a problem when used fully passively.
It seemed to have been a good competitor regardless, and it's sad that it got mothballed.
