Google has announced the Google Pixelbook, a new high-performance Chromebook, which combines parts of a laptop, a tablet, and a smartphone.

Pixelbook is the thinnest, lightest laptop Google has ever made, at just 10.3mm and 1.1 kilograms. It has a 4-in-1 design: You can use it as a laptop, fold the keyboard underneath to watch your favorite show, read your favorite book or take notes in tablet mode when you're on the go, or prop it into tent mode as you follow along with a recipe in the kitchen.

It has a 12.3-inch high-resolution touchscreen display, a thin keyboard with soft-touch keys and a backlit design. The trackpad uses new, special touch-processing algorithms to make sure you can navigate with accuracy.

Pixelbook starts up in seconds and won't slow down over time. Chrome OS provides a secure computing experience, with multiple layers of security and automatic updates. Pixelbook uses Intel Core i5 and i7 processors and plenty of RAM. Google offers storage options of up to 512 GB, and Google Drive will sync your most recent Google Docs, Sheets and Slides to your device. Pixelbook's battery lasts up to 10 hours and if you run low on juice, 15 minutes of charging gets you up to two hours.

Alongside Pixelbook Google is introducing the Google Pixelbook Pen, a responsive stylus which gives you a comfortable feel when you are sketching and writing. Pixelbook Pen uses machine learning for handwriting recognition, and Google says it has reduced latency to just 10 milliseconds. It also has 60 degrees of angular awareness and 2,000 levels of pressure sensitivity.

Pixelbook is the first laptop with the Google Assistant built in. Just say "Ok Google" or press the dedicated Assistant key, and you can talk or type to find answers or perform tasks. You can set a reminder, check your commute, look up a basketball score, open a new document, or find an email. Google Assistant also gives you hands-free access to your music and entertainment and allows you to control your smart home to turn up the thermostat or turn down the lights.

You can also use your Pixelbook Pen to get help or take action on what's on your screen-just press and hold the button on your Pixelbook Pen and circle an image or text. You can look up words, find out more about a picture, add an event to your calendar, and more.

It's not just the Assistant that makes the Pixelbook a helpful laptop. For example, when you don't have access to WiFi, Pixelbook can automatically connect to your Pixel phone's data. And you can ask your Google Assistant on Pixel to send an email to a colleague when you're out and about, and then ask it to find their reply on your Pixelbook when you get back to work.

Pixelbook is available in three configurations starting at $999 in the U.S. The Pixelbook Pen is $99. Both will be on sale at the Google Store and major retailers, including Best Buy, in the U.S., Canada and the U.K. Pre-orders start today.
