When I went to the store to decide on the size the day after launch day, I was carrying my usual case with my 2018 15inch (I carry my 12", 13" M1 Pro, or my 15" on various days). That 16 is literally feels heavier than my entire bag with the 15", charger, phone, mouse, a couple of accessories, some papers, and a bunch of random stuff combined.
There is no way anyone who needs to carry it daily can reasonable use the 16". Sooner or later, he/she would regret it and have to go back to something more portable.
