From a technology or engineering perspective, I have no idea how to work with Apple.
And for audio production - I'm just a dabbler, really, but I've been able to do some really impressive things with just GarageBand and a Fender Mustang Micro amp-plug over USB-C. It "just works" unlike my experience on Linux recently, where there are lots of little bits that are genius, but I couldn't manage to figure out how to get a basic midi synth working with a DAW that had a UI that was designed for humans. (Jack is amazing, though - being able to do arbitrary audio filter chains with random pieces of software is seriously cool.)
I continue to be impressed by ChromeOS. With the Linux development environment (Debian VM), it is a brilliant work environment.
Add Android apps as well and ChromeOS is an awesome convergence platform. There are Chromebooks that are high enough quality that I don't miss anything about Apple OS or Microsoft Windows.

For specialty use-cases, driver support will favour Windows and Apple OS.
And gaming is still Windows-first, although Linux is improving.
The MacBook Air is nice but it still too expensive for most people that only want to browser the web, use social media and edit a few documents once in a while. Their advantage in chip power and efficiency is not enough because people buying this won't make use of the power anyway and will rarely use it long enough at once for battery life to matter that much.
Technically a lot of stuff for linux audio is amazing; it just lacks the level of polish to enable someone to actually just use it out of the box.
