I find the Apple Watch MOST useful in bed. We don't have a clock in the bedroom (like to keep it pitch black), so it's nice to know what time it is.

My wife is a super light sleeper, and I get up first, and the watch gives me a perfectly silent alarm.

I have 4 kids, and the watch makes the perfect flashlight for when you have to get up at 3am and check on someone. It's nice and dim, instantly available, and you still have two free hands (although they messed this up a bit with the sleep mode in the most recent version).

Not specific to Apple, as always.

But implemented with care, as always.

You can switch between a white light and red light. The light automatically dims if you look at the watch and brightens when you aim it away. You can turn off the light by putting your palm on the display.

This is called User eXperience, which is what Apple excels at. Other companies quite often have the exact same features before Apple does - on paper - but the implementation is haphazard at best.

I wear a watch to bed, but then again, I did even before watches got clever. These days, I like it for the sleep tracking and knowing I can get alerted or have my alarm go off without waking my spouse.
