I miss the shape that Logitech incorporated into several models years ago: MX518, G400, and G500. It seems to accomplish much of what this mouse is trying to do, distribute the click along the entire finger and support the thumb. I still use my MX518 at work and my hand just naturally wraps around it like a glove. It makes full contact with my entire hand, every finger rests naturally in contact with the mouse and the only thing touching the mousepad is the base of my palm. Unfortunately Logitech seems to be focusing on looks and gizmos these days instead of solid products, they seem to have no interest in making another mouse in this shape...
