For a long time iRex iLiads used the pre-Vizplex EInk film, which did fade in the Sun. So I think their June 2008 response (presumably about Vizplex EInk screens) is based on what they had to say over and over about the iLiad.

Vizplex film is not supposed to fade, but there have been cases where it does. It is hard to know what fraction of Vizplex EInk screens fade, because most people don't read in the Sun.

Amazon replaces new Kindles if they fade in the Sun. I don't know what they would do if you took 6 months (say) to notice the fading. The fact that replacement works, i.e. you will typically get a 2nd Kindle that does not fade, demonstrates that iRex is wrong. It is not "natural" for Vizplex to fade, but rather it is a manufacturing defect.
