A few months ago I spilled a full mug of coffee all over my white macbook keyboard (no cream or sugar, tho). I didn't notice I'd knocked the mug over (it was behind me) but after a few seconds the monitor went black and the light on the power cord died. After a minute or so of me dabbing at it with a tissue like an idiot, my coworker told me to take out the battery; I picked it up and coffee spilled out the battery bay. But I took it out and set the machine on my desk to dry over the weekend.

Monday I came in, put in the battery, turned it on, and everything worked fine. And I mean everything, even the CD drive. I'm typing on it now. For comparison, a guy I know had the same thing happened to his thinkpad with a cup of plain water, and it just died.
