Trackpoint/clit-mouse is awesome.
It has a higher learning curve, but far more speed and control than a trackpad. Basically, I have not yet met a trackpad user who is not
painful to watch as a trackpoint user.
- You can have pixel-level precision
- You can have fast movements from edge to edge of the screen
- You can use it without moving your fingers away from the keyboard
- You can use it without moving your elbows or arms around
+ It is therefore great for small laptops, small spaces (in airplane seat, on a bench, etc)
Basically, far from being vestigial, my boss has been advised that a trackpoint-equipped laptop is a "condition of employment" for me.
