"The poll shows that those who own smart TVs connected to the Internet actually spend less time accessing Internet content through their TV than those who do not own a smart TV."
This doesn't seem to make much sense. If one makes the logical assumption that those who don't own smart TVs spend no time accessing the internet through their smart TV (since they don't own one), then how do people who DO own smart TVs spend even less time accessing internet content through their smart TVs.
Group A spends zero time accessing internet through a smart TV (because they don't own one).
Group B spends less time than group A accessing internet through their smart TV.
How can you spend less than zero time engaged in an activity?
The smart TV isn't the only way to access the internet using a TV set, they are using some external box and a dumb panel to do so. If you watch Netflix Instant on a PS3, then there you go, you're accessing internet services without a smart TV.
I think it's an indication that the built-in feature isn't very well regarded, for whatever reason, be it a bad internal UI, poor coding, limited options or what have you. When I looked at getting a TV last month, whether it had smart TV features weren't even a consideration.
