I sold my nearly maxed out 16" MacBook Pro for an M1 Air. I hated the 16" with a passion, but the Air is my favourite computer I've ever owned.
It sounds like a criticism, but the best thing about it is that it gives me absolutely no cause to ever think about it. I don't get irritated by it being burning hot and loud as hell because it's always cool and silent. I don't have to worry about battery life because it just lasts all day. I don't constantly bump stuff on the Touch Bar because it has actual function keys.
It just gets the hell out of the way and lets me do my job. That would be enough, but it's also drastically faster than the 16" at literally everything I do day-to-day, which is nice.
