This article discusses the growing demand of using touchscreen interface. Consumers are now seeing touchscreens in a wide variety of electronics, not only in competitors to the iPhone from Sony, Samsung, Motorola, LG and T-Mobile, but also in desktop PCs, printers and copiers, televisions, and MP3 players. Teens, if they don't have a touch-enabled phone, PDA or MP3 player already, often use touchscreen cash registers or kiosks in retail or other jobs. Even young children are often familiar with the concept from playing games on the multimillion-selling Nintendo DS, a touchscreen-enabled handheld video game system. Both students and teachers alike are becoming increasingly comfortable with using a screen as an interactive, hands-on interface in their daily lives, and are coming to expect it in their school's technology as well.
