I was checking out my MagSafe thing today, and I saw this. I was shocked, seeing as my charger NEVER moves. It is behind my desk, and the only time I move the cord is when I charge the laptop. First I saw the gap in the wiring, showing exposed wires, then I saw the very small melted part on the other side. Needless to say I have scheduled a Genius Bar meeting to see if they will replace it. Do you think they will?
