To my knowledge, Boeing has until now refrained from installing pointing devices in airliner’s cockpits.
The typical home cockpit on the other hand runs on several PC’s. Each of these requires a mouse or some sort of pointing device. I decided early on during the building process that a mouse (even a fancy, Laser-equipped one) was too ungainly a sight to be allowed in my cockpit. Besides, a mouse requires quite a bit of space to operate. In the early days – and probabely as an unconscious homage to my arcade gaming days – I experimented with track balls. In the end I settled for touchpads. They are stationary, require little space and can be incorporated into the existing structure without looking too goofy.
Today, thanks to an ingenious little network utility called Synergy all 7 computers in my cockpit are controlled by just two touchpads. The first is installed left of the throttle, the second to the right of the joystick.
