Pros

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
The ball is large enough for turning it to feel like physically rotating an object.
Pro Rechargeable battery
The battery is rechargeable and lasts up to two months on a single charge.
Pro Tracks well on all surfaces

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 Scroll can sometimes jump around
The wheel can sometimes have an issue with "phantom scroll". It may cause the page to jump around/scroll some on its own.
