@futurebird There's one place where I find it pleasant to use, and that's the snooze 'button' of my alarm clock - basically the entire top curve of the thing is a giant capacitive 'button', which also doubles as a nightlight toggle when double-tapped, and I can successfully use it half-asleep without looking!
I'm not sure it would be possible to have such a large physical button without having it be super unreliable (needing to press it at a particular angle etc.), and it also requires a lot less pressure to have it be capacitive. But this is admittedly a very specialized purpose.
