I do this on my iPad with Magic keyboard and I'm a die hard command line user otherwise.

I think the reason I started doing it on the iPad is that the keyboard focus is sometimes inconsistent, so clicking or tab-tab-tab-enter is slower and less reliable vs. just touching the screen. Definitely feel the gorilla arm though.

My 3 year-old never had access to tablets or phones but sees us using phones all the time. So when he gets curious and touches the laptop screen (something he does with our phones occasionally as well), he's shocked to see it doesn't react.
