Wine and Laptops

Wine and laptops don't mix.  I was also told by a helpful Apple Store employee, that if I was to spill anything on my laptop in the future, to spill water.  Wine eventually corrodes the hardware.  Good to know.  Perhaps if I spill another glass of wine I can then clean it with water?  I was also convinced the next time that I replaced the laptop would probably be related to Sam doing something to it.
The best part is, the laptop was open and I was not using it,  it was my first glass of wine, and not even particularly good wine.  Not sure what the moral to this story is.
