I am using a Magic Trackpad, and I have turned the sensitivity all the way down in System Preferences, but it's not slow/insensitive enough. I have a gaming mouse that has custom DPI settings, and I can make it so that moving the mouse about 6 inches across the mouse pad moves the cursor on-screen only about 100 pixels, which is closer to what I want, but I can't seem to find a way to do this with the trackpad.
Can someone point me in the direction of a method to slow down the cursor further while using a Magic Trackpad? Perhaps there is a piece of software out there that allows further customization of the Magic Trackpad's performance, or some similar solution?
