I would say the vast majority of people use wifi for desktop. (Not myself personally except on the third floor of my house). You might be surprised by the percentages.

also don't underestimate the power of stealing your neighbor's internet. I have a fun little router that's named "dontstealmyinternet". I kept the router's default passwords but have it blocked. It gets about 5 attempts a month from new machines.
