<h2>The MacBook</h2>
<h3>It's the future of the notebook</h3>
<p>With the new MacBook, we set out to do the impossible: engineer a full-size experience into the lightest and most compact Mac notebook ever. That meant reimagining every element to make it not only lighter and thinner but also better. The result is more than just a new notebook. It's the future of the notebook.</p>

<h3>Engineered to the very last detail</h3>
<p>Every new Mac comes with Photos, iMovie, GarageBand, Pages, Numbers, and Keynote. So you can be creative with your photos, videos, music, documents, spreadsheets, and presentations right from the start. You also get great apps for email, surfing the web, sending texts, and making FaceTime calls — there’s even an app for finding new apps.</p>

<h3>Entirely new ways to stay in touch</h3>
<p>Apple Watch makes all the ways you're used to communicating more convenient. And because it sits right on your wrist, it can add a physical dimension to alerts and notifications. For example, you’ll feel a gentle tap with each incoming message. Apple Watch also lets you connect with your favorite people in fun, spontaneous ways — like sending a tap, a sketch, or even your heartbeat. </p>
