I have to tell you, I've had exactly the opposite experience. Apple support has been not only willing to acknowledge bugs, they also talked to me on a highly technical level, unlike most customer service experiences I've had. More than one time, they've pleasantly skipped the scripted crap when it was clear I had already followed those steps. In this way, I uncovered a bug in the Mac version of Matlab that went as far as a conference call between Mathworks, Apple, and me when we determined it was a Leopard bug, not a Mathworks one.

I'm not being purposely contradictory here, either. It's precisely experiences like this that have kept me a loyal, returning customer.
