I can tell you that I was just thinking today what a delightful computer this M1 MBA has been for me, and I only have the base 8 GB $999 model. Right now I have it set up with 3 desktops in Spaces:
1) Personal stuff like Messages, Mail, and Calendar, as well as whatever else I need for specific tasks like photo/video editing, streaming video, music, etc.
2) Work stuff like Slack, Teams, Outlook, etc.
3) Study materials in Books and Safari
They're all three pretty much open all the time unless one of them needs to update. I never have any slowdown in performance or really anything other than a buttery smooth experience, no matter what I've asked this machine to do.
It also continues to wow me with how cool it operates and how efficiently it uses battery power. I still only have to plug it in once a week, even as I ask more and more of it. I've never felt it get any warmer than slightly above room temperature.
I have never loved the laptop form factor due to the lack of all the things I listed above. I've never even LIKED laptops for most of my computer-using career. I LOVE this Macbook Air. It feels like witchcraft to have a computer this powerful, battery efficient, and cool-operating even under heavy load.
