I also use the Connexion Pilot-Pro 3D mouse. I find that now when I don’t have it, I find my left hand automatically reaching for it. It is an incredibly useful device when access to 3D surfaces is required. The ability to automatically zoom in and out, while rotating or translating helps to keep the flow moving without unnecessary navigation commands. Sorry if this sounds like an promo piece for the 3D mouse, but it has changed how I do my design work. Patiently waiting for this functionality!
