Opinions are good and yours is valid. But having owned both devices I tend to think the M2 Air 13" is one of the better portable computers that Apple has made. The size is great for traveling and using on an airplane or train. It fits well on the tray table. The screen is bigger on the M2. I like the full size function keys. The performance has been excellent for my needs.The M1 MacBook Air will be remembered as one of the best computers Apple ever made.
After using the Air I attempted to use the new MacBook Pro. I found it heavy and too thick compared to my M2. The difference in screen brightness was not an issue. Speakers, who cares? I use headphones. Speed makes no difference for my use.
For me trading in the M1 Air for the M2 Air was a good decision. I cannot speak for others as to each their own preference.
And I am off-topic. Apologies.
