Flying: What are the best tools out there?

[maradine]

Just like a mouse, except the ball is on the top, not the bottom. Some trackballs are finger balls, and the buttons are on the outside for thumb and pinky. Some trackballs are thumb balls (see: Logitech Trackman Marble), and the buttons are more mouselike.

edit: looks like the Marble is now sold as a finger ball. This is what I meant: http://www.logitech.com/en-us/mice-p...trackball-m570
