@VoxSmart: Are you sure your TV is actually powered off, and not in some "standby" mode? I would probably unplug it just to be safe. After all, it can't listen in on your conversation if it has no power. Then you can remove your hat.
@Albert: I agree. With today's powerful and cheap technology, there's no need to rely on other people's servers to do everything. Take a TV, slap some flash memory into it, give it an ARM processor, make sure the software codebase is not overly complex (we don't need huge, RAM-hogging apps for most purposes), and it will do wonders.
I love my TV... it's not a "smart" TV, but an ordinary TV that can't do much without an external player/receiver/console/whatever. Hurray for my TV not being able to connect to the internet in the first place!
Now then, let's fix (or better yet, repeal) section 1201 of the United States Digital Millennium Copyright Act, so that we can flash these TVs with better freedom-respecting OS's without fear of getting sued.
