Itac’s Mouse-Trak evolution may be pretty to look at, but it’s not very easy to use. The contoured design of the Mouse-Trak fits nicely in your hand and provides excellent wrist support. The trackball is easy to control, but its six programmable buttons are not. You can’t program the buttons’ functions through a control panel. Instead, you must program the functions with the buttons themselves – a very arcane process with only confusing documentation as an aid.
Worse, there is no way to program the equivalent of a control-click, which means you can’t use contextual menus without having to reach for the keyboard. Also,
double-click-dragging is an uncomfortable operation.
