No matter how many wireless products you use, you probably still have several wires coming off your laptop. If you want access to a printer, scanner, and synching bases for your mobile devices, it's hard to enjoy the look and convenience of working at a computer without wires.
Things can really get ugly if you work in your living room, if you've gotten yourself a sleek desk with no room for wires, or if you want to be able to use your computer in more than one place; spreading out on the dining table one day and curling up on the couch the next. When you want a workspace that disappears at the end of the day, wires can definitely be a problem.
