It's nice to be able to throw a movie from the plex server on there with my SO and have a stay-in movie night with some popcorn. Especially during covid lockdown we did this almost weekly with movies, documentaries from youtube or netflix, and tv shows we watched together. A computer screen doesn't really provide the same experience.
On Black Friday I found a deal for a new TV and picked it up, but it was a Roku smart tv. I couldn't find a way to get it working without creating a Roku account so I made one with a dummy email address and then disconnected it from the wifi. Only use it with the Chromecast, which we can use for plex/youtube/netflix without trying to futz around with the UI on the TV.
