Yeah I don't think the Air is really the premium Apple laptop by any stretch.
Not to be an evangelist; but on my M1 Air I found VS Code to be a pig (plus I had to run both universal and native M1 versions) so much that it was finally motivation to try neovim like I kept seeing all these people promoting. Wouldn't say i've gotten as used to it as quickly as others, but I can argue that its at least extremely lightweight in comparison, plus i'm not working under the license VSCode has.
I used Smultron for yonks as well; very good app.
One thing I like about neovim (and its taking me ages to learn & improve) is being keyboard first and having less time with fingers away on mouse etc, its helped my concentration, as has full screening my terminal session and not having anything pop up in eye lines!
