Kensington SlimBlade Trackball vs Orbit Wireless Trackball with Scroll Ring

The Kensington SlimBlade Trackball and the Kensington Orbit Wireless Trackball with Scroll Ring are both stationary trackball mice designed for office use, and they perform similarly well, but with some key differences. The SlimBlade is wired-only and has significantly better click latency, but it's not as portable even though it doesn't come with a detachable wrist rest like the Orbit Wireless. On the other hand, the Orbit Wireless has five CPI presets you can cycle through to suit your preference, and it connects wirelessly with Bluetooth or its USB receiver, so it's much easier to travel with. It also feels more comfortable to use.
