I just spilled half a can of cherry coke in my keyboard and the buttons seem a bit more sluggish than they used to be, though I suppose I should be happy my keyboard survived at all. :) It makes me wonder if the keyboard would survive a quick fall into a puddle, or a lake, or a journey through the rain, falling into instead of having something fall onto... maybe when I get a new keyboard I'll give it a try and see if this truly is an immortal piece of equipment.
Speaking about keyboards: I've never worn one out. I have a fifteen year old keyboard for my old Mac that still works perfectly. In fact, the older it gets, the easier the buttons get to click. Instead of being worn out by old age it is being perfected into a more efficient clicking machine. The keyboard from my old (though not that old) computer still works. The one that came with the one I'm using now hasn't aged a day in a few years, I keep the old as backup, but I should probably have a backup computer instead. They have a much shorter lifespan.
Still some people seem to find a need to swap keyboards every now and then. Do they accidentally spill some liquid on them every once in a while until they seize to function? Maybe they impulsively break the keyboard across their knee after getting killed in Battlefield? Maybe the keyboard starts looking so dirty they can no longer touch it in fear of the bacterial infestation it's keys have given birth to? IDK, it just seems to me that keyboards don't break, unless they are broken intentionally. Here's to another decade with this one. Banzai.
