Never, ever, ever buy a television described as smart. For any reason at all. All of the solutions are miserably pathetic. All of the solutions are riddled with bugs, design omissions and potentially nasty security zero days. All implementations have little to no update support from major third parties.
And, in many cases from many companies, the units spy on you as aggressively as could be to sell data for marketing purposes.
"Smart" tv's are lose lose lose lose. You pay more, you get inferior software, inferior hardware and ultimately have your privacy abused.
EDIT: To be fair, I love my Vizio dumb TV I just got. 40" 1080p dumb TV for $167 inc. taxes this past black friday. Got a HDR/4K Roku for an additional $70 and this TV is beautiful and the Roku is so much impossibly better in both hardware, software and third party support than any "smart" solution ever could be, and costs far less than the "smart" upgrade!
