SAN FRANCISCO—After a year of hibernation, Google's flagship Chromebook offering is back! At the company's hardware event in San Francisco today, Google announced the "Google Pixelbook," representing a new generation of Chrome OS device.

The Pixelbook is full of "firsts" for a Chrome OS laptop. It's the first Chromebook with a seventh-gen Intel Kaby Lake processor. It's the first Chromebook with the Google Assistant built-in, in the form of a hardware button and an "OK Google" hotword when the screen is turned on. And the Pixelbook is the first Chromebook with a pen: an optional $99 Active Electrostatic (AES) stylus called a "Pixelbook Pen."
