Just got my n9 1 week.
the case i ordered (before i even got it) has not arrived yet...

this morning i'd been reading a pdf on the train on the way to work, so i know there was nothing wrong with it then
between then and now it's been in my otherwise empty pocket or lying on my desk face-up
literally nothing happened to it that could cause any scratches in any way
yet a few minutes ago i feel this nasty bump when i ran my nail over the screen...
indeed, there's a small scratch there, about half a cm
what makes it worse is that it is all too visible when the screen is white, then the scratch is brightly colored pink/light blue, changing as you move the phone

how the hell did this happen?
how does a perfectly straight little scratch appear seemingly out of thin air?
