I’ll give you that one. I don’t know about finding unsecured networks, that would be enough to make me return the TV, but the two Samsung TVs I have take about 30 seconds for their input menus to go away. The menu from my Shield or whatever little device I have on my office TV are loaded, but the “Select your input” kinda menu fills 20% of the screen for about 30 seconds and it’s annoying.

That said… I’m never in that much of a hurry so it doesn’t really bother me (though it is a minor annoyance). I don’t blame you if it bothers you, though.
