I don't get the whole "Smart" TV deal. TV is dumb, you sit there, drool and watch it while you get fat. We've had Apps for ages here in Quebec at least. Our local cable co has been doing "smart" TVs with Apps for decades now. It was called Videoway early on as an analog service that provided games/weather info/lottery numbers and other oddities you might "want". Here's what it looked like near the end of its life (a screenshot of an old browser showing a screenshot of Videoway...) :
About 20% or so of subscribers actually paid for the thing, which also provided a short lived "Interactive TV" where you participated in the shows (it was actually 4 different angle shots you selected using the remote at given cues by the show), Videotron even required it for "pay channels" to try to force adoption.
Then we got Illico for the digital age. PVRs, Games, channel guide, a bit less stuff than Videoway, they mostly did away with the crap people didn't use. And ... people still don't use anything other than the PVR and channel guide.
If I want to run "apps", I have a computer, smartphone, whatever to do that. If I want to "game" I have a game console hooked up to the TV which doesn't require throwing out the TV when I change it. If I want movies, I have a blu-ray player or VOD from my cable co.
Also, a TV is a monitor. If I want "smart" out of it, I'll hook up a "smart" box to it via HDMI. That way, my 1080p monitor can last for years and I can upgrade the "smarts" every year or whenever there's a worthwhile update, independant of the monitor itself. In the end, I don't see how "smart" TV can work. All of 'em are overpriced, "been there, done that" and no amount of gimmicks (Siri, Kinect) will ever be as efficient as a good old remote.
