If it is a ball mouse, I will replace it. However, these days I probably use the mouse that came with the system since I'm assuming most new PCs come with an Optical mouse for right handed people.
I probablt buy a new mouse if the optical mouse is a weird uncomfortable square shape or it was made for left handed people.
