Last year when Apple updated its 15-inch MacBook Pro, it packed a Core i7 CPU and switchable graphics into the company's iconic unibody aluminum chassis. Apple is upping the ante again, this time with Intel's second-gen Core processor, AMD graphics, a high-definition webcam, and Thunderbolt, a new high-speed connection that can transfer an entire HD movie in less than 30 seconds. Plus, this powerhouse still delivers excellent battery life. Apple kept the price the same as before (starting at $1,799; $2,199 as configured), so how much more do you get for your money?
