<m> refresh </m> in Apple on Tuesday launched a refresh of the 17-inch MacBook Pro, giving the company's largest laptop an eight-hour battery life, a faster Intel ( NSDQ : INTC ) processor, and better graphics capabilities. Apple observers had expected the refresh of the 17-inch MacBook Pro, given that it was left out of Apple's notebook event in October, when the company launched updates of the 15-inch and 13.3-inch systems. The most innovative feature in the upgrade is a new battery that Apple claims will last up to eight hours on a single charge and can be recharged up to 1,000 times, which means up to a five-year lifespan.
