Many Internet Appliances cost considerably less than their PC counterparts. For PC novices who want access to the Internet but don't care about other software options, Internet Appliances are simple, streamlined and friendly. Internet Appliances may be broken down into several different categories, ranging from tiny, handheld wireless devices to larger machines that require a cable or telephone line to access the Internet. The first, and probably the best known, are tabletop devices. These are smaller than a PC, are easily stored, can work with selected peripherals, and provide direct access to the Internet.
None have hard drives.
WebTV, once its own organization, now under Microsoft's wing, was the very first set top device. Although it was originally designed with teens in mind, it has become the option of choice for many seniors who enjoy the ease of use, compact design and large screen. WebTV has grown up with the industry, and now offers several levels of product, ranging from basic to deluxe. Another whole area of Internet Appliance design is the Web Pad or Web Tablet. These are somewhat new to the market, and not as widely used as the set top or desktop devices.
