Ethernet won't last long ? How do you come do that conclusion ? Currently ethernet is the cheapest, fastest, and most widely used technology for home and business networks. With 1GB ethernet currently being employed in the highest-end networks, eventually coming to the home (granted it will be awhile) and the new 10GB ethernet standard on the horizon, how can you possibly say it'll be extinct in about 5-10 years??? Granted coax cable has potential I doubt it will ever be able to surpass the ether.
