I kind of would have expected a $175 keyboard to survive a coffee spill. It doesn't really happen anymore, but as a kid I must have spilled soda on my no-name keyboards once a month, with no ill effects.

One benefit of membrane keyboards is that the membrane would prevent liquids from reaching down into the sensor components.

That being said, I've resurrected my WASD Code keyboard a few times from coffee and water spills. It can be taken apart and cleaned with rubbing alcohol, left to dry, and reassembled pretty easily. I usually do this anyway every 18-24 months at this point for sanitary reasons.
