It has never connected to the internet, and it never will. My long term concern is that google will eventually put cell modems in their tvs, and then using my next tv as a dumb tv will no longer be an option. For now though, this is your best bet.
Other things I can think about is reliability of the screen (like dead pixels), and your family if not clued in may think you present as "poor".
It sucks because its android, but at least its degoogled.
Edit: for a TV, I love my 30 year old Panasonic. Paid $20 for it at the Mormon goodwill. Only 720p, but has the best speakers of any TV I've owned.
Google doesn't do scummy screen spying ("ACR", Automatic Content Recognition).
You can make Tizen much faster by manually uninstalling the Samsung TV Plus app. It runs in the background constantly. "Much faster" is still slow overall, unfortunately.
