Student devices have changed from desk top to lap top over the years, and are now changing again to other types of devices. This substitution is summarized in graph below.

While the number of data points is small, the data fits the Fisher-Pry model well, and supports common knowledge. Desktops are in decline and laptops have reached their maximum penetration of the market. Other types of student devices are rapidly gaining share of the market. While there is data presented in America’s Digital Schools on a number of other student devices, with the limited number of data points, it was impossible to segment the other device category. However, thin client, handheld, cell phones and portable gaming devices seem to be on the decline. While, tablet PCs and student appliances are gaining market share.
