The value of the Vizio 47" Smart TV for $648 (after Amazon Prime discount) is hard to pass up.
Versus...
The Samsung non-Smart 46" with 3D (not that I care for it. It just has it) for $647. I'd have to add a Roku box to get the same apps that the Vizio will already have. A Roku 2X for 1080p is another $60 dollars. So all said and done, this will be $700.
~$700 vs ~$650. I'm leaning toward the Vizio. The picture between the two, when I was comparing at Best Buy, were not so different. The Samsung was better, though, but not by very much.
EDIT: Also, the Samsung only offers two HDMI ports, which is a big downer to me. Even though it's a minor inconvenience, I rather not deal with switchers and whatnot. It just feels like I'd have to gobble together different things with the Samsung versus getting everything in one package.
