Apple revealed the new MacBook Pro Thursday on the 25th anniversary of the release of the first Powerbook. The main highlight is a new, secondary screen, dubbed the TouchBar, and it's essentially a small multitouch screen, which helps with typing suggestions and displaying tools for various apps. Siri is also back, as well as TouchID for security. Apple states it’s the thinnest and lightest version of the Pro to date. The new line of MacBook Pros also sport the quad-core Intel Core i7 chips.
