I am also using UA40D6600(2011 model) ,i bought separate qwerty keyboard (remote control size).
Honestly i also prefer to have normal size qwerty wireless keyboard with a mouse-but need to know the compatability.
Also i need to know that Gtalk & facebook apps support voice over or only message chat /
I have UA40D6600 40" LED TV and love it
What I am wanting to know can you get a wireless keyboard and mouse for it or is there an App that I can down load?
