But I hope Samsung will answer privacy concerns such as others are asking.
http://techvikings.com/samsung-responds-questions-cameras-microphones-tvs/ covers this again and so far it looks like there is no assurance this will not be abused.
"Samsung also reports that it's not responsible for the services of third parties. Another point of criticism is that Samsung in it's conditions, argues that it may use personal data within all its business structures. The Samsung Group counts a large number of international divisions and joint ventures, leaving unclear exactly, which components have access to such data."
Until you are comfortable with such a device in your home, I'd avoid such models.
But 3D is not an issue.
I've heard that if I buy avatar in 3d it won't work on my samsung. I have the Samsung es8000.
