I have been using Linux for several years, but I am going back to Windows myself.

I vastly prefer Linux, but I need LINE (a messenger app popular in some Asia countries). Their Linux app (actually a Chrome extension) stopped getting new features 5 years ago. That's kinda THE deal-breaker for me.

Another minor reason is Dropbox Smart Sync. I can use Selective Sync, but having smart sync is of course better.

(I would rather Windows than macOS)
