@sapphire @ocean @coolboymew @skylar IIRC the Air has only 2 USB-C ports and no Ethernet.
Meaning OS development, specially networked-focused isn't going to be a thing you can comfortably do with it.

And you'd probably need to offload any slightly heavy compilation to another machine due to the shitty thermals of the Air, meaning you'd pretty much need to have access to an actual machine (quite like sysadmins typically do with connecting to servers).
