The distinct irony is that this is why I actually dislike white keyboards as a rule. In my experience, no matter who uses them, they tend to start showing the buildup of environmental dirt around finger impacts pretty quickly. I find myself having to clean the ones at work every 4-6 months, if not more often, with a window cleaner infused rag. Plus, like your experience with headphone rubber disintegration, I find that the ones I've had at home tend to start yellowing on the most used keys.

Needless to say, all my home keyboards are black, black, and black.
