On most android phones that thing is part of the display that contextually hides itself, and doesn't take up extra physical space

"Most"? I've not had a single Android phone where the buttons have been part of the display. A few tablets, but no phones. I'm sure there are plenty of phones that do that too, but I've somehow managed to avoid them for the 6-7 or so Android phones I've owned.

Pretty much every Android phone released in the last 2 years besides those made by Samsung (which is admittedly a large percentage) have had on screen keys.
