Slightly off-topic: I decided to go with a Mac Mini to start playing with AI. My daily driver is a Linux laptop (with a negligible GPU). I also have a few Raspberry Pi machines for backup, and a low-end AWS server.

I was always cobbling together ad hoc network access, to get from one machine to another. Access to my Mac Mini while traveling was a pain. Bringing it with me is ridiculous, and network access was a PITA.

Tailscale is wonderful magic. Free (for my usage), so easy to set up, and now no matter where my various computers are, they are all accessible trivially via a single ssh connection.

So get a beefed up desktop Mac, set up Tailscale, and then use any random laptop, anywhere, to use it headless.
