Horizontal aspect ratio is obviously superior, but the short does show there are some things vertical does well.
But our eyes are getting more and more used to the iPhone’s vertical aspect ratio, thanks to apps like FaceTime.
Held horizontally, the iPhone can do a pretty decent job of mimicking the aspect ratio we’re accustomed to from a lifetime of movies and widescreen TVs.
Then again, I’m not watching anything on a big screen right now, and perhaps not for a long time.
