If you don’t stop to examine your keyboard every once in a while, you might miss the fact that it has become covered with crumbs, grease, and sticky soda stains (not to mention a coating of dust). And that’s not all: A recent study showed that some sample keyboards had more bacteria and filth than a toilet seat!
