I'm referring not to the underside, but to the surface around and other than the trackpad. It is far more grippy and sticky than it used to be or than the MacBook Pro or Air are, and in fact the hand doesn't move easily, for instance, when going from top row to bottom row keys. I don't like the feel of it, which is a matter of taste. I was hoping there would be some workable way to make the surface on either side of the track pad more slippery, so the wrists and hands could more easily slide and move around. A little wax was what came to mind, but I am very interested in any ideas anyone might have. Thanks.
