The good: Updated CPUs and graphics without an updated price; LED-backlit display for better battery life; 802.11n support.
The bad: Minimal configuration options; only 90 days of toll-free technical support; still no media card reader.
The bottom line: Apple's 15-inch MacBook Pro gets a solid under-the-hood upgrade for better performance and longer battery life, allowing the MacBook Pro to put enough distance between itself and the lower-end MacBook to justify its higher price.
