Pros
Pro Comfortable and ergonomic
With thumb and pinky on the buttons and three fingers controlling the ball, the user's wrist lays flat on the table (or on the provided attachable wrist rest).
Pro Intuitive link between ball motion and FPS camera angle

Cons
Con Not a mouse
This is a trackball, not a mouse.
Con Questionable secondary button defaults
The upper left button, which is the hardest to use, is middle click by default. The upper right, which the ring finger naturally rests near, defaults to Back. This can be particularly annoying as the Back button is easy to brush when moving hands between keyboard and mouse.
Con Major RSI issues
Pushing up and side to side with one finger is not a natural thing to do with your hands.
Con Common software glitch comes up when scrolling
The trackpoint "rest point" gets skewed, and keeps scrolling when you release.
Con Not good for people with thicker fingers
Depending on how worn down the trackpoint is. People with thicker fingers will often hit adjacent keys by accident.
Con Requires a lot of force to use
The stiffness of the trackpoint leaves your fingers fatigued after even 2 minutes of use.
