That's a nice vision, but as someone who transitioned from a windows to mac a few years ago, I'm sad to report that reality isn't anything like it.
Office for mac is lightyears behind what windows has. Both excel and outlook miss critical features (just last week I was looking to change the background of an email - seems that's impossible on mac), or are so much worse in terms of performance (~20mb file with pivot tables) that I'm not sure if I'm running Excel on my m1 mac or if it's a raspberry pi.
