Sorry to rain on the Smart TV parade.
But as it stands I am not a fan. The makers issue apps or don't stand behind the apps and well, the story gets worse. I'm not the only one that will not give them a dime for any app or "Smart" today.
So with that out of the way, find reviews (CNET usually has a few) and see if any sway you. Also, why are they offering paltry 1 year warranties? Would you be upset if it failed in year 2?
