I use a wireless mouse because I don't like how the cord restricts 
motion and gets tangled. Also, the cord on the Apple Pro mouse is 
extremely poor quality, Jobs chose looks over lifetime. It's thin, 
and eventually fails (breaks open or shorts out, I've gone through 
two mice so far). The Apple Bluetooth mouse doesn't suffer from those 
problems. It does use up batteries, mine last about a month. They 
would last longer if I would remember to turn the mouse off at night.

I also use wireless networking here, as ethernet was producing QRM on 
HF, I am on a second story and the router was in the basement, that 
length of cabling was radiating some RFI. Wireless solved the 
problem, and makes it easier to position computers around the house.

If you do have issues with your transmitter causing malfunctions in 
computer equipment, I would humbly suggest tracking down and fixing 
the actual problem (RF in the shack), not the *symptom* by bandaiding 
one particular peripheral. Perhaps it is a transmission line issue 
between the rig and antenna, maybe even due to an impedance mismatch. 
It may also be a grounding issue.
