macbook pro problem - "water damage"- Really?

I just sent a 6 month old macbook pro off for warranty repair. I received a call from apple telling me that they would not honor the warranty because of water damage. My computer has never been subjected to any liquid either by accident or intentionally. I'm wondering if the seals on the computer are faulty?

Has anyone else had a similar experience? This repair has been quoted to me as $755 without tax.

I'm interested in finding anyone else who has run into this problem with the hopes of getting apple to re-think their manufacturing and testing process. Maybe they screwed up and don't want to admit it?

Laptops are meant to be taken from place to place aren't they? They should be able to withstand humidity and be safe from "water damage" even in the rain if they are kept in the safety of their protective carrying case shouldn't they?

Let me know if you have had this problem too so I can see if this is a common occurance.
