So the other day, I spilled water on my MacBook Core Duo. I have a keyboard cover thingy though, so minimal water got into the computer. However, the enter/return key no longer works, which I think is because of some kind of water damage. Luckily, I still have this other enter key that I previously though useless but actually isn't. However, I also use my enter/return key a lot (Adium, pressing enter instead of clicking OK, etc.). So I was wondering if anyone had experience with the durability of MacBook keyboards. If possible, I'll attempt to repair my current keyboard instead of buying another one, which on eBay starts at around $40-50US.
