We here in the Apple Garden know that Apple takes all our usage data and trust then that they are used anonymously. But Apple has no access to data when it is encrypted, they even warn you when you encrypt your data that you need to safe the keys yourself, they can only delete everything if you lose them.
I was in a similar situation, but I got a MacBook M1 for literally everything but PC exclusive gaming, and I kept my gaming rig dual booting windows (on the HDD) and Pop!_OS (boots automatically, saved on SSD).
Why did I get a MacBook? I just wanted it. I‘d probably throw SteamOS on the gaming rig one day and use steam-link with an Ethernet cable to stream the games to the MacBook.
And yes, Linux is really easy to use nowadays. I’ve been thinking of throwing a lightweight distro onto my parents laptop. They only use Firefox so they won’t even notice it lol
Ah yes, the Portable Monitor - the Pornitor
