I disagree that it's visceral on mobile. First, close your eyes then toss your phone up in the air with a spin, catch it and try and then try and click on 'I'm done for now'. Feels exactly the same as "I'm still working!". "Visceral" should be reserved for things with physical buttons that make a satisfying ca-chunk and you're sure, blindfolded, that you didn't press the wrong one. Not slippery glass bricks.
