It's not good business to detract sales from your high end flagship product though. The lack of matte screen s a deal breaker for some folks who "upsize" to the pricier model just to get it.Firewire came back and there is no reason why AG/Matte (or Gloss) can't be provided as a BTO option. did it for the 17, they can do it for the 13 & 15's.
Besides... most PC laptops don't come with screen options either. It's the path of the industry these days.
