So what your saying is wireless is so much simpler.
But with a wired unit you save original purchase and not risks the chance of interference problems were you will constanly get stressed over until you buy a new computer even more money. All to save a one time 5 minutes of install, if takes longer than that you should have your LBS do it for you.
