On the surface the RAZR V3 was just an evolved version of the clamshell phone, but it truly was a breakthrough device. Motorola used aircraft-grade aluminum and new design techniques to achieve an unbelievably slim .54-inch profile. This 3.4-ounce wonder also threw out the traditional dialpad for a precision-cut electroluminescent keypad with a Tron-like pattern. The specs were pretty beefy too given the RAZR V3's size, including a VGA camera, 2.2-inch color screen, and Bluetooth. Motorola nearly ruined this brand by churning out too many sequels, but revived it with the Android-powered Droid RAZR and Droid RAZR Maxx.
