A Germ Free Computer Mouse?

I noticed an ad in an ergonomics magazine for Contour Design's new "MediMousePro."  It's a 2-button optical mouse with a polyurethane cover that "allows it...to be disinfected, helping curtail harboring and spreading of infectious agents."

I'm not sure I need such a feature for my home office, but I suppose it makes sense if you work in a hospital or environment that gets a lot of traffic.  There's not much on the web about the mouse yet, but here's a PDF I found from the company: http://www.contourdesign.com/508_compliance_cdi.pdf
