I'm excited about the re-vamped MacBook Air, and am considering a 13" model. Much to my dismay, no illuminated keyboard anymore! I understand keeping certain options only for the Pro to encourage upgrading, but this one may be a deal-breaker. Since the keys are the same style, would it be possible to take off all the keys, swap out the board underneath and replace it all with the backlit counterparts from the older MacBook Air? What all would be involved? Thanks!
