Hello! I have an early 2009, 17-inch MacBook Pro. Today I noticed what looked like a small hair on the screen, but when I tried to wipe it off, I discovered it was actually a tiny crack in the screen (that extended the entire length of the screen when I touched it). I have a few questions about this. First, will Applecare cover this? I have Never dropped, hit, or damaged the computer. Second, if they won't, how much will it cost to replace it? Third, is this a common problem? Like does this happen ofter on larger screens? Thanks!
