These new laptops are thinner and lighter. That's no surprise, although they don't come close to competing with the slimmest high-end Windows laptops. The 13-inch model is 14.9 mm thick and weighs 3 pounds (about 1.36 kg), while the 15-inch model is 15.5 mm thick and 4 pounds (1.81 kg).
The keyboard here uses Apple's butterfly mechanism, which allows for shallower keys and a thinner body. Using a very shallow keyboard made sense in the very thin 12-inch MacBook, but it'll come as a bit of a shock for Pro users, who are used to the deep, clicky physical feedback of the current MacBooks.
Just 60 pixels high (and 2,170 pixels wide), the Touch Bar could be a tool with the potential to be the Swiss Army knife of laptop input, changing itself on the fly to work across different apps, imitating a series of touch buttons, control sliders and even jog dials. This is Apple's answer to the touchscreens found on most Windows laptops.
By default, the Touch Bar displays a command strip view with brightness, volume and other system control functions. When another Apple app is launched, including Photos, Mail, or Safari, the command buttons roll up to the far right side of the strip, leaving the rest of the space free for app-specific commands, which can take the form of buttons, sliders, or dials.
The far right side of the Touch Bar has a small square set aside for a Touch ID input. That's the same fingerprint technology that's in current iPhones, and lets you log into the system and make payments via Apple Pay. You can do that already if you have a MacOS MacBook and an iOS10 iPhone, if the two devices sit close to each other, but in the new MacBook, it's a self-contained system powered by Apple's built-in T1 security chip.
While the keyboard on the new MacBook Pro models have the same shallow key travel (an industry term for the distance the key moves downward to register an input) as the version on the 12-inch MacBook, the new "feel" of the keys, and how they register a click gives the keyboard a more substantial feel.
Taking the place of function keys, the Touch Bar brings up autofill choices as you type, lets you edit videos in Final Cut Pro or straighten photos in the Photos app. Users can also customize the Touch Bar by dragging and dropping new tools into it.
