I still don't understand why an informed consumer would want to buy an Xbox One. It's not that MS might snoop on you while you're not playing games. Microsoft has actually patented methods to do so. Examples: awarding achievements if you watch commercials (link), restricting number of viewers and by age of viewer (link), and even detecting your mood and deciding which ads to show you (link).

Microsoft is also a US company, and as detailed recently, the NSA already regularly monitors unencrypted intranet data inside big corporations such as Google and Yahoo.
