If someone else has the problem 100% of the time, and you have the problem 0% of the time, I think it is reasonable to presume the fault lies with them or their environment (or at least, not the hardware).
I have exactly the same problem, the middle connector on one side always gets burned. A quick search on google shows that this is a common problem, so I would actually check if this is a common problem or not before defending Apple.
