Technology changes so fast, it's easy to inadvertently end up with a bunch of older systems. And cell phone tech changes every year at least. I live alone but I have a network set up. And don't forget things like Internet gaming devices, iPads or iPods, media centers, VOIP phone systems, DVR systems, wireless printers, external storage drives or servers, all of which connect to a local network as well. I probably have at least 10 devices on my network in total, not all in use at the same time, but all of which can connect to my local network as needed. </tech head>
