Android TV works great as well. I have it running on an old Chromecast that cost less than $50 new.
While I still prefer running a plain Wireguard VPN if possible (i.e. when there's a publicly reachable UDP port), the really big advantage of Tailscale over other solutions is that it has great NAT traversal, so it's possible to run a routing node behind all kinds of nasty topologies (CG-NAT, double NAT, restrictive firewalls etc.)
I have run into the firewall problems before. Even seen them that block authentication but -if already connected to the tailnet before joining the WiFi in question - will continue to pass data. OpenVPN would not connect and couldn’t handle the IP address switch.
At worst, I turn on phone hotspot, authenticate, then switch back to WiFi. A purely serendipitous discovery on my part, but a very welcome one.
