with the removal of speaker grills,the only thing that is problematic with dust and water is the keyboard,everything else could be sealed i believe
but yeah ik we'll never get a water resistant mba sadly ,because
1)for some reason EVEN the ipad don't have any sort of IP rating
2)as efficient as ARM is,the pros will always need active cooling.and i dont see apple giving water resistance to its mba lineup and not for the pros..
3)dunno how complicated it would be to make the keyboard membrane waterproof...if that's possible
