An antibacterial mouse. What a great idea!
Unfortunately, the remarks about how grubby a typical desk is prompted me to try to shake some of the muck out of my keyboard… eugh.
Seriously though, I’d like to see this feature a standard part of mouse (and keyboard) design. It’d also be good if the manufacturers designed input devices to facilitate cleaning. Most modern (i.e. optical) mice are OK, but keyboards, quite frankly, are pretty hard to clean; most of the time you find that you have to actually take them to pieces to get them properly clean, and it isn’t always as easy as it looks getting them back together.
