> Why do they keep making wireless trackballs?

Much more convenient to use with laptops, or with setups where wires are inconvenient for reasons other than mobility while in use (e.g., any situation where you would use a wireless keyboard, which is also usually stationary when in use.)

I wonder what the breakdown is then between wired and wireless keyboards? I have to think the wired ones are far more popular.

I've had a wired Logitech trackball for many years, and I worry that on the day it breaks I won't be able to replace it.
