I bought my Iliad about one month ago, I love it and use it extensively.
The screen was so good and white with no trace of any ghosting after one month.
I forgot to turn it off one night and behold, in the morning it was off but the screen was not completely white, it had the shutdown screen + the last book page.
When I've powered it up the screen had a lot of ghosting. Using the ghost-busting pdf I was able to remove most of it but the rectangle of the book page can still be seen.
This is very annoying, The SW should be able to do complete shutdown when the power is running out, it is expansive device (800$) and I've expected more.
Many posts on the forum and a personal question regarding the possibility to leave the iLiad on for long periods of time was always answered "It will not hurt the screen, after few refresh it will all go away...". THIS IS NOT TRUE - BEWARE!!!!!
I've always shut down the device in fear of ghosting and the one time I forget it burns some parts
