The Uproar from Samsung was the first cell phone with MP3-playback functionality. A whopping 64 MB of memory was available for roughly an hour of music, and the device connected to the Internet for Web browsing. A handful of other features, including voice-enabled dialing and personal-information management, made the Uproar a fine tool for both work and life. Sprint retailed the Uproar for $400 in 2001.
