The only reason I upgraded is my wife “stole” my M1 air. I bought a loaded M3 MBP and then they came out with a 15” Air with dual monitor capabilities. Kinda wish I had the air again. It’s not like I move it around much but the form factor is awesome.
I love the air form factor. I do serious work on it as well. I have used a pro, but the air does everything I need without breaking a sweat, and it's super convenient to throw in a bag and carry around the house.
Same here, my M1 Air still looks and feels like a brand new computer. Like, I still think of it as "my new MacBook". It's my main machine for dev work and some hobby photography and I'm just so happy with it.
Interestingly, Apple still sells M1 Airs through Walmart, but not their own website.
