Congrats, I also bought the 16/1, though I did buy it from Apple... reason? Color. I know, petty. But Midnight was just not happening for me. So I got starlight and am super happy about it.
So far excellent experience all around. It does everything I want. Only possible nitpick? Possible - not feeling the supposed great battery life. I spend a lot of time on a networked mac mini which I access through the MBA, and after a few hours, I'm surprised to see how much the battery on the MBA has drained. It's probably just an illusion, but the M1 MBP I had seemed to me to last longer (while doing things like streaming Netflix/HBO etc.) - I gave the MBP back to Apple because it had problems (keyboard), but the battery life was outstanding... not feeling this with the MBA/shrug/.
