Coffee's not as good, though. I can't even consider their flavored versions as coffee anymore...more like 2x sugar milk with some strange artificial enhancer.
They also don't have baristas. You can't drink serviced coffee if it doesn't come from a barista.
Also, McDonald's is fast food...I'm assuming the WiFi is motly for smartphones since they really can't expect anyone to spend more than a couple of minutes (it wouldn't help reach daily sales otherwise).
