The iPhone has many best-of-class features, but the big one is its super-high-resolution touchscreen that you operate using a pointing device you can’t lose: your finger.

And what a display it is. We venture that you’ve never seen a more beautiful screen on a handheld device in your life.

The iPhone’s built-in sensors also still knock our socks off. An accelerometer detects when you rotate the device from portrait to landscape mode and adjusts what’s on the display accordingly. A proximity sensor detects when the iPhone gets near your face, so it can turn off the display to save power and prevent accidental touches by your cheek. A light sensor adjusts the display’s brightness in response to the current ambient lighting situation. The iPhone even has a gyroscope for advanced motion sensing and GPS sensors so your phone can determine where in the world you are. Our favorite example of motion sensing is that our iPhones rarely ask if we want to join a Wi-Fi network when we’re in a moving car. That’s a smart smartphone.

In this section, we take a brief look at some of the iPhone’s features, broken down by product category.
