Motorola MicroTAC 9800X
1989
The MicroTAC 9800X was not only the smallest and lightest mobile phone of its time, it was the first to feature the trend-setting "clamshell" type design where a mouthpiece flipped to cover the keypad when not in use.
Featuring a dot-matrix LED display, very advanced for the day, the MicroTAC and its immediate variants remained in production well into the 1990s and formed the basis for much of the world’s idea of what a "cellular phone" looked like.
