Don't look at the screen on the new Apple MacBook Pro if you are a Windows user. You might never turn back. The display sports 5.1 million pixels and, like the iPhone 4S and iPad 3, has a crisp fidelity that makes most notebooks seem quaint--and blurry. This updated model weighs 4.46 pounds and is only .71 inches thin. Plus, the high-end 15-inch model comes with a zippy Intel 2.6GHz processor.
