I got rid of my MBA 2013 in 2018, in hopes to get a proper replacement, but the unreliable keyboard and weak spec stopped me from getting one. Eventually, I got tired of waiting. Tried linux, first at work (with System76/Pop!_OS), then at my home laptop (Manjaro and Pop!_OS), and I don't think I'm coming back to Apple.
Yes, linux requires some adjustments to your workflows and playflows, but I was surprised how little. And as with everything, the more you are at it, the easier and more natural it becomes.
The only thing I'm really missing is iOS development. However, that might be a good thing, and if I really need to do it I've got a MBP 2012 waiting for me in the basement (although, it will be obsolete really soon).
