More than a decade later and phones no longer required Popeye-style muscles to be carried around. Motorola dreamt up the Startac, one of the first notable clamshell designs - a form factor arch-rival Nokia has shunned by and large to the present day.

Among the other innovations the Startac brought to the market was the vibrating ring, and the device also sported a relatively new invention that operators didn't really think would be a big hit with consumers - the text message. In 2004, Motorola brought out a 10th anniversary edition.
