LG's webOS TV review?

I was looking on Amazon today and I was surprised to see that LG's webOS smart TV is currently for sale. Has anyone seen any professional reviews yet? I know we saw a preview at CES but I'm itching to see how the finished product looks and feels.

In a world with Google's Chromecast, Apple TV, Fire TV, Xbox, PS, and Roku is there still a need for a smart TV?
