Thank god you're not in charge.
I agree. Seriously.
Ignoring the fast that his is just ridiculous nit-picking, Apple would obviously negotiate their price with their vendor based on the total quantity. That some are black and some are white is of no concern to the vendor at the quantities Apple is dealing with.
And the guys Toyota example is even more ludicrous. He clearly doesn't realize (and yet is the type that knows EVERYTHING he needs to know) that having "TOYOTA" etched into the die that is stamping the bolt heads ANYway doesn't add a THING to the cost.
In small quantities, sure, that would be extravagant because you could just use an off-the-shelf die. In the quantities someone like Toyota uses, they would have dies specifically for their own use anyway.
If the guy HAS to bitch and moan about something, I wish he'd pick something legit.
