Is it worth it? I think this story explains it all.
During the beginnings of the older Mac's Steve Jobs directly oversaw the creation of the hardware, software, you name it, of the Apple computing business. While going over the new Mac prototype, which the engineers had slaved over, and was working fine, he tells the head engineer, "I don't like the memory, it is not symmetrical. Move x to y, and p to q. It will look better that way." The engineer argues it works just fine, and nobody is going to open the computer anyway. Steve Jobs pretty much tells the guy to change it, which the engineer is arguing whether or not it is electronically possible. Long story short, the engineer was right, the memory chips could not be repositioned. Steve Jobs had to settle for less.
Why is this important? Besides the obvious that Apple prizes form over function, it says that you are really paying for a look, and even though you may never see it, you do pay for it.
And if you believe in my conclusion above, then you believe in the tooth fairy.
PS: The story is true.
