I'm getting old, and too much regular mousing leaves my hand in a lot of pain, especially if I'm working on something fiddly and precise (like an SVG project, or editing video). I'm currently using a Kensington Orbit Fusion wireless trackball. So far, it's working out pretty well…but not with Kensington's software.

My trackball was right-clicking on its own constantly until I uninstalled KensingtonWorks and installed X-Mouse Button Control instead. You can also read more about XMBC here.
