Keep in mind the battery is not enough for a movie. So the entire family will also be plugged into a wall wart. Mind the wire for any bathroom breaks!

It's a 2 hour battery with a dedicated cable and looks easily swappable in seconds.

The running time of the CD-ROM was designed to play Beethoven's 9th symphony in its entirety. You would have thought Apple would plan the battery life to allow you to watch all of Avengers: Endgame, or maybe Oppenheimer, without pausing to swap the battery.

Yes, even for that family of rich Apple executives, it will get tired by the third time.

For a 3500$ device? Fantastic!
