Apple on Tuesday released a much-anticipated update to the MacBook Pro. The new models are a major upgrade in speed and use up to a 2.66GHz Core i7 that can clock up to 3.33GHz using Turbo Boost. They also switch to new GeForce 300M graphics that, using NVIDIA's Optimus technology, can grab up to 10 hours of battery life by switching to Intel's graphics when not plugged in.
