PC Perspective posted a review on the Apple MacBook Pro 2.3GHz Sandy Bridge 13.3"

After Apple released their new line of Macbook Pros on Feb. 24, many users thought Apple would do a basic performance bump of the system's hardware and send it out the door to consumers. They predictably included Intel's latest Sandy Bridge processors, which integrates an HD Graphics 3000 processor with the CPU, but they also became the first company to adopt Intel's new Thunderbolt technology. The combination of Sandy Bridge and Thunderbolt is just the tip of the iceberg for this year's Macbook Pro lineup. We ordered one of their entry level 13" models to see firsthand how these new capabilities boost system performance and usability.
