How about posting some highlights from the article, instead of just a link?

Edit: On topic - It's nice to see that the SmartGlass app isn't being limited to just Windows 8 devices.

Hahaha yeah.

Smartglass wouldn't affect my buying habbits but it's still something I'll try out.

its already a pretty good app. I look forward to it on the xbox one even more.

This is major. There's a lot of potential there.

From potential of multiple airstrikes in titles like The Division (as demonstrated at e3 on one smartglass) - to casual & social  trivia/gameshow/board game types where friends or party guests could just pull out their phones and join the game - if developers choose to find a way to utilise this to its full potential - this could develop entirely new ways to play.

While maybe not as earthshattering as the invention of the analogue stick or something equally significant - it's still a cool little thing.
