I don’t know if it is always the fastest. I know they said android, but for example on not too old Apple phones (pre-usb c), I had the impression you could get better throughout on wifi compared to a cable connection. Maybe that’s just apple trying to squeeze money on proprietary connectors, but other manufacturers seem to copy their worst takes sometimes though.

I have not heard of any orgs replacing windows with Mac. This is for consulting and IT. To my knowledge, it is still something only available to execs and higher management. What sector was this for?
