If you’re using the mouse for gaming or graphics, you will want a mouse that is technologically advanced in optics. The reason for this is an advanced optics mouse is going to be much more precise in its movements (great for graphics) and much more responsive to the smallest movement of the user (great for gaming). For instance, Microsoft has a mouse that scans 1500 scans per second. This is a very responsive very precise instrument that will handle itself well in both graphics and gaming capacities.

If you are just looking for a nice comfortable mouse that will get you in and about the web without need of such precise movements, you may want to downgrade the optical features to a less costly version that is still capable of handling your requirements.

The trackball mouse comes in ergonomic and non ergonomic styles. You will need to decide of the more expensive ergonomic designs are worth the extra cost to you. If you frequently spend time on the computer, you may want to consider the ergonomic designs as they will make computer work much less stressful on your hand, wrist and arm and will minimize the fatigue you feel when working long hours.
