Gone are the days of that ancient computer clicking a whiring off in some room. Everything is a computer today. Your TV, Stereo, Phone (of course), etc. Heck, even your computer is a computer.

This brings a lot of complexity into the home network. The bigger and more extravagant the home the more impressive the network. You have media servers, multiple TV's, laptops, security systems, phones, etc.
They need to be connected at all times.
