Wrist pain brought on my first ever change of mouse design. I'm trying to get used to this trackball mouse that I bought today, but it's hard to relearn movements I have done probably millions of times.
Aside from hi-tech eyeglasses, it's taking more and more specialized equipment to operate this computer. You can see my IBM "Model M" reproduction keyboard in the images below. It's huge, heavy, and has buckling spring keys which give auditory and tactile feedback as I type. It solved my carpal tunnel years ago. Here's a prior post on my pain-solving keyboard.
Between the keyboard and this trackball mouse, maybe everything will be cool again. 😎
I'm a gettin' old! :p
