On the iRex Blog there is an
interesting article about the internal workings of the iLiad, a bit of information about where and how it is produced, and what differentiates the iLiad electronics from other E Ink devices.
It also mentions that iRex is looking into E Ink's latest Vizplex technology; in fact, they are testing it right now.
