The Good The second generation of Apple's Retina-screen MacBook Pro adds internal upgrades to its Wi-Fi, Thunderbolt, SSD, graphics card, and CPU. The result is a faster laptop with better battery life and a lower starting price.

The Bad The changes are internal-only, and not significant enough to upgrade if you have last year's version. At $1,999 to start, this is still a very expensive laptop. Both the 13-inch MacBook Air and Pro have much better battery life.

The Bottom Line The slimmer body and higher-res screen of the original Retina MacBook Pro were a revolutionary leap. This revamp adds modest internal upgrades for modest improvements, but price cuts to both the 13-inch and 15-inch models sweeten the deal.
