Are there any benefits besides a nice GUI? I'm fairly comfortable with my linux desktop as an interface. TBH the most frustrating part is the iPhone shortcut app I made which I strongly believe is less about me and more than Apple is actively trying to be annoying (I recently had an update that required a minor change because the dictionaries in Shortcuts is idiotic)

Also, I heard that you can install Tailscale on it[0], so that can act as a gateway which is nice.

It's something to be aware of if you already have the mac. It's nice to be able to have people over and they can share what's on their laptop with everybody without everybody having to huddle around one machine.
