The iPad has many best-of-class features, but perhaps its most notable feature is that it doesn't come with a physical keyboard or stylus. You can get them as options (Apple’s first-generation $99 Apple Pencil, the second-generation $129 Apple Pencil, and the Smart Keyboard, which starts at $159), but they aren’t required to use your iPad. Instead, every iPad requires a pointing device you’re intimately familiar with: your finger.

Every iPad ever built has a beautiful Retina screen, easily the most beautiful screen we’ve ever seen on a tablet.

The screen rotates — that is, unless the screen orientation is locked. We tell you more about this feature shortly.

And we love the iPad’s plethora of built-in sensors. It has an accelerometer that detects when you rotate the device from portrait to landscape mode — and instantly adjusts what’s on the display.

A light sensor adjusts the display’s brightness in response to the current ambient lighting conditions. Then there’s a three-axis gyro that works with the accelerometer and built-in compass. And most models — since the iPad Air 2, iPad mini 4, 9.7-inch iPad, and all iPad Pro models — also include Apple’s Touch ID sensor or Face ID. These features let you unlock your iPad with your fingerprint (Touch ID) or just by looking at it (Face ID)! We talk about both in detail later.

Last, but definitely not least, all iPads since the third generation include Siri, a voice-controlled personal assistant happy to do almost anything you ask (as long as your iPad is running iOS 6 or later).

In the following sections, we’re not just marveling about the wonderful screen and sensors. Now it’s time to take a brief look at the rest of the iPad’s features, broken down by product category.
