I haven't read a good response yet to the concerns brought up last year at http://hdguru.com/is-your-new-hdtv-watching-you/
Since makers are mandating that you connect and log in to use the smart features it's pretty clear they get to see exactly what your set is being used for without an opt out or "do not track" option.
The makers have a lot invested in this so it's clear there's a lot of unanswered questions.
I'm goign to purchase a 55" Samsung LED and I see that the ES8000 is almost the same price as the F6400. If you had a choice which one would be the better choice?
