I recently ruined my laptop with orange juice,
I find that coke is not as good for that. Therefore, Coke is safer, trust me, my wireless keyboard still works despite a few splashes.
If you are in an emergency, then purchase/dl iWork from the MAS. When you get the disc, contact iTS and explain the situation, they may give you a refund due to the circumstances (but no promises here!).
iWork on a disc is a seperate version from what you will get in the MAS, so they are not the same thing.
