As electronics enthusiasts gather in Las Vegas for the International Consumer Electronics Show this week, a new Gallup analysis finds Americans falling into four groups according to their ownership levels of the electronic devices already available. At one end of the spectrum, 31% are "Super Tech Adopters," who report broad ownership of the major computing and entertainment devices on the market. At the other extreme, 28% are "Tech-Averse Olders," who own little more than a basic cellphone and DVD player.
