Internet appliances were contrasted with any general purpose computer, but unlike personal computers, internet appliances were low cost and low margin products, usually using highly optimised low power silicon specifically built for internet use. Modern smart phones and tablet computers do approximately the same things, but are more powerful, more successful in the market, and generally not classified as Internet appliances.
History
Internet appliances were promoted by a variety of technology companies during the 1990s but, as the price of full-featured computers dropped, never met the market expectations. Jim Louderback would later describe the concept as one of the "eight biggest tech flops ever".
Early in the 21st century a new breed of household devices, such as Vonage Internet Phones, PenguinRadio's Internet radio, and IPTV boxes, began to use the broadband connections in PC-independent ways.
