The 3D Connexion mice also offer fine grained tuning of just about every function imaginable. From motion speed, to macros, you can control it all. It even automatically switches presets for each application you are in. For those of you that don't think glowing blue lights are cool, you can even turn that off. (Lets be honest, you aren't going to do that, are you?)
I love this thing. It has made me faster and more efficient. It's also an excellent presentation tool because it allows you to make presentations less "herky jerky" and more smooth and immersive. Just don't try to re-create the Star Wars trench run scene unless your viewers have strong stomachs!
