Analysts and marketers define portable media players (PMPs) as handheld devices whose lead function is the playback of video and whose color screen is 3.5 inches or larger. They can also play back music and display still images stored on embedded flash memory or hard disc drives. Some PMPs are based on Microsoft’s Portable Media Center (PMC) platform.
Video-capable MP3 players, in contrast, are handheld devices whose main function is music playback, although they offer video playback ad a secondary feature. These devices include current video iPods and feature screens no larger than 2.5 inches, according to analysts’ definitions.
