"Go fast". The set top Androids are also pretty fast. Also, as someone said, who reboots these days? (though it's a selling point for a media player replacement)

"Stream HD movies without a hitch", ok, that's a selling point, though my cheap Android phone does well enough on "good enough" quality, so I'd expect the Android set top boxes or equivalents to do just as well.

"Go straight online to creating, sharing and enjoying. Chrome devices come with built-in apps for editing photos, creating documents and presentations, and video chat, so you can get everyday tasks done right out of the box."

Ok, though the Android boxes do that too.

"Google+ Hangouts. You can also integrate multiple chat accounts with apps like imo or eBuddy. "

Not a selling point for me (what is a Hangout?)

Edit: I tried explaining myself. Why the downvote instead of a rebuttal? (I can accept those)
