What do you mean? You mean like the surface cracked and stuff due to some kinda hit or like fall of the device on the ground?
It's super smooth and the reader has always been in its case. Never fell, nor never had anything poked against the screen :/
Actually, it looks more like a "Line-out" to me -->
Icarus Illumina HD - Screen issue page.
However I don't understand why such thing would happen a week after having used it.
So maybe I really broke it then? If so I don't see how.
EDIT: Nope you are right, I confused the screenshots on the above page. It looks just like a broken screen. Damn.
