Yeah, it's funny and sad; much of my friends list is "playing" Netflix when they're on. The players who are on games get top-level on the Social menu, EVEN IF THEY'RE AWAY, but if I go into the actual submenu, all Friends are shown, and most of them are watching NetFlix Streaming.
Personally, I prefer my AppleTV for viewing film and tv content, it's much easier to navigate, is much more responsive, and the TV apps on 360 all feel really clunky, and have that lowest-bidder stank on them. Like, Amazon Prime Streaming on startup shows a full-screen low-res single frame shot of my Xbox Avatar for no apparent reason. Search functions start sending the text string before you have finished inputting it, stuttering your search speed. It just feels crappy.
