I use an external mouse and keyboard with my laptop whenever possible because the ergonomics of having your screen and keyboard at the same level are awful, and I've got enough back pain as it is. I use a mouse sometimes and a trackpad other times - but the optical mouse does better without a mousepad. Why are you making aluminum mouse pads? Metallic surfaces (whether matte or reflective) are the only ones where the optical mouse is completely unusable without a pad, in my experience.
