I refer to it as the pencil eraser. Once you get used to it, you realize it has the more control than the touchpad. Its main benefit, for me, is that you never have to move your hands out of typing position.

Agreed. I haven't had the awesomeness of a dual touch touchpad, but I've had both normal ones and "the nub", and the latter is vastly preferable.

Try using it with a sniper rifle. You'll change your tune.

the only thing that was quicker 'maybe' about the touchpad was speed of learning, and ease of use. The 'nipple' is much faster and more precise if you invest more time in it. much like linux ;).
