Ugh annoying headline. “Buttonless” implies the buttons are disappearing, like the home button. The articles says they might be using “solid state buttons” which, I think, are a bit like the Macbook trackpads, there’s no real button but it still acts and responds just like a trackpad button.
The lock and volume buttons likely will still be there, just won’t physically move, and use haptic feedback instead.
You speak from the perspective of someone who’s either always had enough RAM, or not enough work to do.
