Eeek, that might be trouble later. I remember pouring water on my PC notebook, it was only a tiny small bit, and it didn't seem to have any problems the first day.. then the next day the keyboard starts to mess up, randomly keys would press.. then half of the keyboard didn't work.
I'm not sure if it's a hardware problem or a driver problem (could be both) but it's very slow now, and seems to have video problems because of it (and this small amount was just on the keyboard)
The best suggestion I found was to turn it off and keep it off and just put it on it's side so the water drips out.
