I'm pushing 38 and an executive and iPads of various generations (which I have refreshed yearly) have been my main working/travelling machine right since the release of the very first versions. I still have a i7 MacBook, a specced-out quad-core 2012 MacMini (with dual CinemaDisplays) and a trashcan Mac Pro, but somehow the iPad (currently in it's 11” iPadPro incarnation) is always my favourite tool both because of its portability and because of its focus. You'd be amazed what I can do locally on this machine: construct, symbolically solve, and make predictions based thereupon mathematical models being one of the things that surprise people most. Writing and locally executing Python code. Storing versioned copies of business plans.
