Apple TV vs XBox One - killer features

Apple TV has all the major cloud video providers. Airplay + Mirroring.

XBox One has all the major cloud video providers. What is the equivalent of AirPlay + Mirroring here? I've seen Windows 8 have a "Play To" charm that can send media to a DLNA device, which I assume the XBox is. But what about Mirroring? Is that what SmartGlass is for?

I just think that 50% of Apple's success is coming up with catchy marketing terms for their tech, and Microsoft let's theirs languish. I hope they get the advertising right this time.
