I have seen pictures of people's lcd and it completly destroys the screen, but i think mine is cracked but it doesn't actually effect the screen. on the bottem of the screen there is a 1/2 inch long gray line, very thing, going on an angle to the right (its about in hte middle of the bottem part of the screen. THis appened a month ago, i heard about apple's policy about lcd screens so i just bought an external screen and have been using that. I am in college and i use my laptop in the lecture hall for notes during biology. I am always looking at the crack, making sure it doesn't get any larger, and quite literally, i watched about 1/4 of an inch to the right of the crack a few pixels grouped together died, then about another 1/4 of an inch to the right of that another small grouping just died. Is this a crack in the lcd screen? I love my macbook and treat it like an egg.
