It sounds extreme, by I personally believe that mice destroy the wrists of programmers - that's one of the reasons why we love programs and interfaces with tons of keyboard shortcuts - along with being faster, it's easier on the wrists.

In addition, good keyboard controls can make or break many programs. If you take a look at a program in the adobe suite, you'll normally notice two things. First, that using the program with the mouse generally involves awkward mouse manoeuvrings. However, keyboard shortcuts can eliminate 90% of this.

Third, do you personally recommend using a trackball? I've been experiencing some mild wrist pain lately and am looking for something better than a mouse.
