Apple on Tuesday announced major updates to the Retina MacBook Pro, adding new processors and lowering the prices for its laptop lineup.

In addition to those changes, Apple is also simplifying its MacBook Pro lineup, reducing its offerings to two standard configurations.

The new $1299 13-inch Retina MacBook has a 2.4GHz dual-core Core i5 processor, 4GB of RAM, Intel's Iris Graphics, and a 128GB SSD. According to Apple, the new 13-inch Retina MacBook Pro is 3.46 pounds, which is 0.11 ounces lighter than the previous 13-inch model. The new 13-inch model is also 0.71 inches thin, which is 0.04 inches thinner than its predecessor. Apple claims eight hours of battery life.

That $1299 price tag is a $200 drop from what Apple used to charge for its entry-level MacBook Pro.
