I have used a mouse all my life so this is the first time I've used a trackball and I like it. It's not so difficult to get used to and once you do it is much easier to use than a mouse because you don't have to drag the device around. It is much easier on the hand musculature than a mouse because you don't have to put effort into holding it still while clicking and you can comfortably rest your hand on it during use.
