Touchscreen is the must-have feature in latest cell phones, particularly smartphones. And the world's two most celebrity companies going head-to-head against each other are obviously Apple and RIM.

Although Bold doesn?t have a touchscreen, rumors are swirling around RIM and its Thunder device that's slated to compete better against the iPhone, and yes, with touchscreen.
