My Wrist Used to Hurt

I had a theory that Apple’s Magic Mouse, possibly exacerbated by the Magic Trackpad, was killing me. I use the mouse at work and the trackpad at home, and the pain in my right wrist has been steadily increasing during the past several months.
Three days of field tests that began with swiping a larger mouse off the desk of a coworker who has been out of the office lately seem to support my theory. When the pain eased after a single day of use, I quickly ordered a Logitech Professional MX. After three days, the pain in my wrist has practically vanished.
Something else that pains me is that I adore my Magic Mouse and Magic Trackpad. Alas, I am passing those on to others and digging the Pro MX.
