I want to buy one just to raise the signal that Linux support is important. When these machines were announced I switched to Fedora as a daily driver on my high end gaming rig. It’s been awesome. I still have to go back to Windows for music production unfortunately. I may switch to Mac for that so I can completely abandon Windows. I run an optical HDMI cable from my office to my TV and get to play games and use Linux…
I also work in music production (for video games) and fully switched to Linux + FOSS about a year ago. I'd say it is a lot more doable if you make electronic styles of music. Harder if you make classical styles, as many of the big sample libraries don't support Linux yet. Just in case you're interested, here's a list of everything I use: https://johnoestmannmusic.com/tooling/
Lot's of interface simply work best with Window.
