When I was considering what to run, I found LineageOS TV provided the best experience for being able to get all the other TV apps, and even Jackbox Games. Many TV apps offer some content free with ads, which can be taken care of. Android TV interface only shows Android TV apps in the main app drawer though.

I loved Debian with KDE Big Screen on the pi for the customizability. You can run scripts like fetching tv schedules right on it (or you can just do this on your jellyfin server), and generally you have more customizability. I run PWAs as well via Firefox. I found Steam Link difficult to get working unless on Buster or earlier.

For remote, I tried out all the ones on Amazon, and found USB connection to be most reliable, and there’s one that has a keyboard on the reverse, and an option to do voice control from the remote that’s a major 🔑

I do this today with my Librem 5 and a 1 TB uSD

Been happy with my Purism Librem 14, and soon they’ll have a 16". I think today, I’d probably buy their 11" tablet. Perfect travel size and you don’t need to put it away during takeoff and landing of flights.

Just did my part 🚫🎞️🇨🇦

I find having the full OS is useful, and this KDE environment proves great https://plasma-bigscreen.org/

If you want to preserve your battery, follow the same principles for any battery, avoid having above 80% and below 20%. I’m not sure for KDE, but on GNOME I have a GUI utility that lets you set this and enable/disable with a toggle.
