Honestly, no thanks, I'd prefer to do all my networking on my mobile or computer, having it on my console is just overkill. Not to mention its much easier to customize your 'networking experience' outside of your console. I mean, who the hell wants to use the onscreen keyboard or pay sixty dollars for a crappy peripheral to edit your facebook/twitter? 
 
The movie streaming is a great feature, since Netflix doesn't work up here in Canada so this is a great alternative. Personally, I never go to rental stores anymore cause its inconvenient to drive all the way to the store, spend thirty minutes deciding what to rent, then heading back home only to lose interest in watching a movie. Now I can be lazy and stay home to do the exact same thing without the long trip. 
 
The music is w/e. I use my iPhone for that.
