Right to the point...
The "Devices" charm is not the same as "Play To", though the play to function is a feature of the Devices charm... but what's the difference? If you're playing a playlist in XBox Music on your Surface, and many of the songs in your playlist are local and don't have cloud versions, when you "Play To XBox 360", only the songs available ON XBox Music will play.
But, if you open you're devices charm, and select "XBox 360" you're now streaming the entire playlist directly from your device to the XBox, including songs not found on XBox Music, and you remain in the app, without being bumped to XBox Smartglass.
I've also noticed while watching videos on certain websites in IE10, the XBox 360 becomes an option in the devices charm. Now I sadly only saw it come up on a video that got stuck in an endless loading loop (and it doesn't show up for YouTube videos), but I'd imagine it can also send media to the XBox 360 for viewing in the same method as AirPlay on iOS.
You can also use the devices charm to send photos to the XBox 360, allowing the Surface to become a slideshow controller. I haven't had the chance to explore what other apps support the devices charm, but the option to send content to the XBox 360 will only appear when there is active content on screen that can be sent.
