Nothing else is void, just the scratch in the screen will not be fixed. Now if for some reason you had another screen issue and it could be proved it was not related to the scratch, it would be covered.
Is that the new unibody MacBook with the glass-top screen? How did aluminium scratch glass?
Moh's Hardness Scale
Aluminium = 2.5 to 3
Glass = 5 to 6.
What's funny is that whenever you tap the screen of an MB, MBP, or iMac at the store with your nail, the sound it makes actually sounds like you're tapping on plastic. It's not like tapping on a window.
PMMA:
* has a density of 1,150–1,190 kg/m3. This is less than half the density of glass, and similar to that of other plastics.
Sure. Have a wallet?
As did this..try dropping it on your screen and see the results
If an issue arises with your display, and they trace it back to this scratch - then they won't do anything.The display warranty all together? Or just for that specific issue?
The glass on a Macbook Pro is Acrylic Glass ((C5O2H8)n)

I was under the impression that the OP has a matte screen, no glass. Not sure what all the talk about glass i about...That said, the good news is that it appears that only the GLASS has been damaged, not the actual LCD panel. Iresq or ifixit might be the most economical solution in terms of a replacement. or maybe it can be "buffed" out?
In General Practice, the entire screen warranty has been voided, as they will blame any problems on the Mark.
