I prefer hard wired for anything that is going to be a solid work machine.
That includes my mouses, and keyboards. I hate having to replace batteries, and getting error messages about some of that bullshit (signal weak, can't find signal, and so on). I typically have batteries in the house, as I keep them for emergencies like power outages, but it just annoys me.
I use wireless internet and hardware for non-essential machines around the house or office. But if I am working on the machine for any length of time, I prefer all hard wired. I simply have no patience for the other aggravations that come with wireless routers, and hardware.
