Yeah, i think that was it. But i think it was also mentioned on the iRex forum, in a discussion involving Karel's post in the i-to-i blog:
http://i-to-i.irexnet.com/2007/11/09...ays-different/
... which states:
"In the coming weeks we will compare the display performance of the current iLiad with a Vizplex™ prototype and analyze the differences. So stay tuned."
Again, no updates of any kind since then.
Edit: It's worth noting that iLiad's screen never was described as a gen 1 e-ink display. According to iRex, if the first Sony Reader is first generation, then iLiad's screen is second and the Vizplex third.
