Until the manufacturer stops supporting them, and the service provider changes out from under them (YouTube killed off various old clients a while back by retiring an old api, say). People keep TVs for a LONG time; you&#x27;re probably looking at an expected lifespan of 10 to 15 years. I suspect that smarttvs may ultimately be a fad; a little box makes more sense given the replacement cycle.<p>This is especially true if the gaming aspect takes off; a 150$ box that is refreshed every year or so looks more attractive than something built into your 600$ TV that is supposed to be replaced every 15 years.
