Double meh. I've read the article and about a hundred posts, and I still can't see what this gadget is for, nor why I should want one.
Why would I want to see stuff from my phone on the TV screen? If I want to use NetFlix I'll get it over my broadband connection. How many films does it take to burn through a typical mobile data allowance?
Is there some kind of content that's only available on phones? Anything else, I'll view on one of the computers in the house. If it absolutely has to be seen on a TV-size screen, and it's not available through the TV's internet connection, I can connect a computer to the TV.
