Apple announced that it has updated its high-end MacBook Pro laptops with faster processors, better graphics and more memory space.

The laptops are still available in three models: two 15.4-inch versions that retail for $1,999 and $2,499, and a larger, 17-inch edition that costs $2,799. But with Tuesday’s update, the lower-end 15-inch model is now equipped with 2.2GHz Intel Core 2 Duo processors (previously, it had a 2.16GHz chip); the higher-end 15-incher and the 17-incher now come with 2.4GHz processors, up from 2.33GHz. These new processors are indeed Intel’s latest Centrino–or “Santa Rosa”–chips, which were introduced in early May.
