Maybe I should be single, but this is my preferred way to speak on the phone when I’m not bothering anyone, and the enviornment is relatively quiet. It frees up my hands for a better range of motion if I’m doing anything else, and it removes my common accidental hang-up when my ear or face touches the display.
If the environment becomes noisy or people are around, I of course switch back to old-school DJ-gesture phone call mode.
