Apple rolls out new Macs

 In coming months, Apple is expected to roll out a new iPhone, which is likely to give the world’s most valuable technology company another shot in the arm and offer a challenge to rivals such as Google Inc and Research in Motion. The new phone could also propel Apple to leap past Exxon.

While iPhones remain the flagship device, the company touted its new line of Intel-powered Macs and the latest version of its operating software, the multi-touch enabled Mac OS X Lion.
