I will try to resume what juancarlosleo has been posting in various threads here and in irex forums.
Basically he bought one iliad, and after 2 months the screen background turned so grey that the text-background contrast was diminished and it was very difficult and unpleasant to read in it. Then he bought another one, and after 3 months the same happened. He says he have tried to contact the techsupport but he had to wait 2 months for a response. I don't really know, by reading his posts, how was that response.
As a result, he came to the conclusion that the iliad is a far worse device than advertisements make people believe, that the grey screen is not a bug of his units, but a fault in design, fabrication flaw or something like that, something cronic. For him the fact that the screen gets more grey in time is inaceptable in a device priced so high. And he thinks that the people who doesn't talk about the progressive greyeing are either fanboys that don't want to see reality or even vendors that try to hide the product deffects so the sales are not affected. Basically he thinks the iliad is a fraud.
Then he has the intention, in his own words, of sabotaging the irex sales in two ways:
-showing his wasted iliads to his friends so they don't make the same error that him and buy the device.
-talking in the forums about what happened to him, because as i said, he thinks that forums are full of fanboys and vendors that don't see or don't want to say the truth.
The reason he always writes in spanish is that he doesn't know enough writed english to show the full range of his frustration in that language.
My own first iliad is arriving my home in a couple of days and i'm very scared and sad because of the things he has written. But, if my iliad gets dark, not only shall i contact techsupport, but remember to myself, as an usual buyer of different hardwares, that maybe i have disobeyed the golden rule of technology products:
NEVER BUY THE FIRST GENERATION OF A TECHNOLOGY (because is always flawed).
Tough my iliad is a second edition, so maybe i will be lucky
