Why is there a premium added to the antiglare option of $50 if you select this option for a 17" MBP or other MBP's. Is the AG screen truly considered an "upgrade?" Could it be that the economy of scale does not apply here so Apple actually has to pay more for the Antiglare screen since they order a lot less of the AG versus the Glossy screen so the cost is passed onto those who elect to pay for the AG upgrade. I am curious your thoughts as to why Apple has a $50 premium for AG? Thanks.
