Honestly, the term “Smart TV” has such a vague definition that buying one simply by that feature being listed could still lead to disappointment.
What feature are you seeking in a Smart TV? Netflix and YouTube are extremely common, Hulu a little less so, and some apps are only available on streaming boxes like Roku or AppleTV.
