A mouse is a mouse, right? Not when you are working with 3D applications like Maya, 3ds Max, Softimage, AutoCad etc. You will need an advanced mouse like the SpacePilot Pro ($499) which is designed to harness the power of designing with 3D. The SpacePilot Pro features a 3Dconnexion Cap (the large knob) which can be pushed, pulled, twisted and tilted allowing you to navigate a 3D interface. While it also has quick view navigation keys and a full color LCD display which provides visual feedback on what the keys have been programmed to do.
