You know keyboards can be had for like $10, right?
Also I have never spilled water on my keyboard, and I don't understand how people manage to do so. However when I was 14 and had my first PC (a snazzy Pentium II) my friend came over to see it and spilled an entire can of coke on my $100 (a fortune for me at the time) MS Natural keyboard that I had saved up for. Needless to say, it was ruined. It still worked but it was so sticky.
