Yes, the 4.7-inch screen is optimal for me, too. Apple should've kept this screen size and made the bezels as small as possible.

This applies to the SE, too -- keep the screen size and makes the bezels smaller.

In a way, the iPhone XS is a step back from even the iPhone 6, because it's bigger.

Apple seems to be doing things arbitrarily nowadays, like Dell and other OEMs that Apple (fans) loved to mock years ago.
