Nokia 9210i Communicator
Nokia's second attempt at a flip-open QWERTY-keyboard device was released in 2002. When the device was snapped shut, it was like an old school brick-like device that was almost eclipsed the side of a person's face. But when flipped open horizontally, the keyboard would emerge and a separate screen would appear above, similar to how a laptop works but with a much smaller screen.
A true business and enterprise-focused phone, it was powered by an 52 MHz ARM 9 processor and operated Symbian 6.0 on a Series 80 user interface -- a design unique to the Communicator range of phones. But it was thick, heavy, and if dropped could probably register somewhere albeit low on the Richter scale.
