Reader, I am very sorry that you still don't get it. This is about servicing a customer constituency. While you can make what you believe to be your airtight case that "there are no performance problems, thus this ws titally unnecessary and out of the goodness of their hearts", you seem more intent on trying to slap down a class of people than to recognize that multiple reasons why Apple acted. You don't have the evidence and, frankly, you won't get it, so you have no ability to comment on what the evidence shows.
I'm sorry that you are not as smart as you think you are, but Apple, on the other hand, IS smart to have finally listened to its PRO-MEDIA constituents. I doubt very seriously you are a creative person. You may think that's a slight, but it's not. You just probably aren't a creative person and thus you are not as sensitive to a persistent oscillating high frequency whine.
I know many engineers who could work with jackhammers in the same room, and as long as the processor compiled the data without error, no biggie. Likewise, "loud computer? who says? It meets the spec. Look right here." That kind of narrow thinking is what makes you who you are. That's fine.
However: Apple is a business, and if your theory is correct -- and it's not -- why in the world would a company go through the trouble to create this fix, set up infrastructure in all those territoris, train the AASPs, produce a quicktime video of instructions -- if it didn't impact their bottom line. You think the costs of this fix are going to be written as a PR line item? I doubt it. Try "Customer Retention" line item and "New Customer Acquisition" or "Litigation".
There's already plenty enough noise coming from these MDD's. What the world needs now is surely not more uninformed noise from you.
Apple did the right thing when it was forced to. And guess what? Everyone of us LOVES OSX and the Mac Platform. I'll bet you $100 I've owned Macs longer than you. So shut your hole.
