CUPERTINO, CA—As expected, Apple today took the wraps off of a completely revamped MacBook Pro lineup for the first time since giving the laptops Retina displays back in 2012. The 13- and 15-inch models come with a wide array of internal and external upgrades and changes, and they continue moving Apple’s Mac lineup in the direction heralded by the one-ported MacBook last year.

The new laptops are thinner, and lighter, with the 13 inch model weighing 3lbs and the 15 inch model coming in at 4lbs.

The single most striking difference between the old and new Pros is that the row of function keys (and, yes, the Escape key) has been removed and replaced with a long OLED touchscreen panel called the “Touch Bar” that can do different things depending on what you’re doing and what apps you’re running. Some users will no doubt mourn the loss of physical keys, though if used well the Touch Bar should bring some of the versatility of software keyboards to what is otherwise a regular hardware keyboard.
