You may find some sensation in your fingers due to using the 'magic mouse' since it uses some of the
same touch-technologies the stand-alone touchpad and the touch pad in portable Apple computers...
To some degree, there is a similar sensation and negative feedback in my fingers from use of the
USB Apple mouse, formerly known as 'mighty mouse' wired version. It is a five button mouse with
dual-purpose scroll-wheel/button; the two buttons (hidden) near the tiny roller ball affect my fingers.
Something I've not quite felt before, and I've worked around electricity for awhile; many years.
{Other multiple button mouse products that do not use touch pad technologies, do not affect me...
I have two other mice that are mostly mechanical with extra buttons plus scroll wheel, as baseline.}
Perhaps the idea to test any new product extensively within the limited return duration is best, to see
what if any issues may result from a trackpad or touchpad built into a device, or a standalone unit that
does similar action requiring conductivity of ones hands or fingers, for the product to function.
There are static-cling protective plastic materials available from several vendors, and their composition
(type/kind) of plastic may vary somewhat. There is a possibility something like that may help, if it does
not interrupt the necessary conductivity of touch for these peripheral or built-in devices to work.
Good luck in any event...! 🙂
