Trackball vs. Tablet vs. Mouse

 

I haven't been posting much because of my hurting arm/shoulder. 

I have been trying to give it a rest.

 I have switched to a trackball and I don't like it (yet).
I miss my mouse. I don't feel like I have good control with a trackball.
I'm sure it will improve as I get more practice.

I wonder if I should try a tablet. A friend gave me

one years ago but I don't have it anymore.
I bet I would like it more than a trackball.
