I have an old laptop with Linux Mint hooked to my TV. Firefox with some bookmarks to different streaming services, Freetube with subscriptions, sunshine/moonlight to my gaming PC and emulators to play some retro adventures with my kids. I remote controll it with KDE Connect from my phone. Works great!
I used to fiddle with Kodi on a Raspberry Pi, but the laptop is so simple and easy to set up, I don't see myself going back.
This looks like it costs more than my old laptop, which I saved from becoming e-waste. But I tend to forget we're already living in the future and hubs like this exists. So, thanks for reminding me, I'll look into it. :)
