This actually is a pretty big deal in my eyes. Never has there been a camera in your house where most of the people will congregate and have the "potential" for capturing a TON of information. It could "potentially" know who you are, what colors you like to wear. How much weight you've gained in the past month. Whether you're sick or you're healthy. What you smoke, what you drink, what you eat, what time you go to bed, what time you wake up etc.. Sure this can be used for good, but could potentially be used for gain.
I also MS has filed for : http://www.gamesindustry.biz/articles/2012-11-06-microsoft-applies-for-pay-per-viewer-patent
Now if you want to buy an MMA fight for you and your friends, maybe instead of 40 bux, its now 120 cause they can count how many viewers are watching.
I am for data collection. It has many useful purposes, but willingly putting something in your home for someone to potentially watch is concerning. What if police/FBI/NSA corner MS because they believe someone commited a crime. We'll maybe they're not using that info for advertising, but hmm, we have all the above details about these people, we better turn it over.
