Here's what the doctor would prescribe for a sick keyboard: the Vioguard keyboard. Though not cheap at $499 to $599 when it rolls out later this year, this contraption may be worth looking into if you consider the fact that the keyboard may have even more germs than a toilet seat.
Setting that image aside, the Vioguard system is an idiot-proof one-button process. Once initiated, a motorized drawer will retract the keyboard into an enclosure and put it through a bath of germicidal ultraviolet light. That's some powerful medicine. Now if only this'll zap our hands clean of bacteria at the same time.
The Vioguard keyboard is intended for hospitals, but let's hope this will spin off into the consumer market as well. Watch it in action below.
