Ok, so it's not as bad as it sounds, and I'm not completely sure it is cracked. It's not even visible at any angle, but if I run my finger to the bottom left corner of the trackpad, I can feel a line where it feels like two barely separated pieces. If I press the corner (1 inch up, 2 inches across) down, it looks as sturdy as a normal trackpad. The tracking is even all around the pad, where the bottom and top left and right corners have limited/no sensitivity, which is the same as a cm strip along the top and bottom of the pad. It happens if I start in the areas and stay there, but if I start outside and go into the areas, they work fine. Is this the same as everyone else? Doesn't bother me about the weak zones much since this pad is huge and I never go to the edge, I'd just like to know if it indicates a damaged part. I included a crappy picture that I edited on the iphone where the red line indicates where I feel the "break" and green lines showing where the sensitivity is low. I took it to an Apple Store where a genius and the manager both were able to feel the line. The genius said since it would be considered a "cosmetic" problem, it wouldn't be repaired. (I didn't notice the sensitivity issue until afterward) They said if it really bothered me, call AppleCare and ask for a replacement. Don't get me wrong, they didn't try to avoid the problem and they were pretty understanding. I'm a bit hesitant to get a replacement because Apple pretty much gave me a huge upgrade by replacing my powerbook with this. Even though I'm a perfectionist, I don't want to bother the company with small issues since they helped me out a lot. Not only that, I don't want to get stuck with a replacement that ends up being worse off than this one. The screen is good, and while I do barely see a bit of leaking light in the bottom right side and some in the left edge, but I had to look hard for it. They keyboard is ok and no dents or scratches in the machine. I may just live with it, not sure at the moment.
