The fact that the StarTac looked similar to the communicators used on Star Trek was just icing on the cake for a phone chock-full of firsts. Not only was the StarTac the first clamshell mobile phone, it was also the first with a vibrate option. At 3.7 in. by 2.1 in. by 0.75 in. and 3.1 oz., it was the smallest and lightest cell phone yet when it was released in 1996.
