A smart fan that listens:
When engaging the voice dictation feature on new Mac laptops, Apple automatically slows the internal fan speed to better hear your voice.

A "breathing" sleep light:
Apple has a patent dating back to 2002 for a "Breathing Status LED Indicator." The patent describes a "blinking effect of the sleep-mode indicator [that] mimics the rhythm of breathing which is psychologically appealing."

Smart caps:
On every MacBook Air (and all newer MacBook Pros), if you hit the "Caps Lock" key, nothing will happen. In order to prevent accidental keystrokes, Apple only turns on Caps Lock if you hold the key for a bit longer.

Hidden Hi-Fi audio:
For audio and video professionals using optical adapters, Apple has integrated a high-fidelity TOSLINK output. As soon as you plug in an optical adapter, MacBook Pros automatically switches over to TOSLINK, enabling higher fidelity, high-definition sound.

Volume and Brightness Bounce:
The next time you adjust the brightness or volume on your iPhone using the control center, give the dials a hard flick and watch as continue to move even after your finger stops. If you flick hard enough, they'll even bounce back a bit.
Hidden magnets:
Before Apple integrated its iSight cameras into iMacs, older iMacs had a hidden magnet centered on top of the bezel. This magnet anchored the iSight perfectly atop the computer. A magnet on the iMac's side bezel held an Apple remote in place too.
A tiny "Do Not Disturb" eclipse:
When you turn on "Do Not Disturb" mode, a tiny crescent moon appears at the top of your screen. Not too impressive by itself, but when you toggle the setting on and off, you'll notice that a tiny eclipse animation happens right before your eyes.
Virtual reflections:
If you pull up your iPhone's Music app and start playing a song, take a look at the shiny knob on the volume slider. The "reflection" on the knob subtly changes as you tilt your phone. Note: Only works with phones running iOS 6 or earlier.
One-finger lift to open:
Apple designs its laptops so they can be opened with just one finger, thanks to that special groove on the front lip. It's worth noting that new devices can take some time to break in before it works.
Predictive "Store" button:
When playing a song in your iPhone's Music app, it used to be dangerous to back your way out through the menu buttons. Going from "Now Playing" to "Artists" often led to accidentally tapping the "Store" button, leading iTunes to pop up.
Now, Apple prevents iTunes from opening from a single tap of the "Store" button when someone is backtracking through the menus.
