"A computer keyboard does, in fact, harbor more germs than a toilet seat. According to a University of Arizona study, office workstations are much dirtier than bathrooms. A computer keyboard can harbor up to 3,295 microbes per square inch, a computer mouse 1,676. Telephones were the worst culprit, with 25,127 microbes. By contrast, the average toilet seat contains only 49 microbes per square inch."
