The comments are interesting too. Here's my take: If you care about your privacy, I recommend against installing software that runs at all times, on a computer you carry with you at all times, that has all sorts of personal information about you, and many sensors to get data on where you are and what you do; when said software is provided for free by a company that profits from gathering your personal data. How much did you pay Google for Android? How much did you pay Facebook for Facebook Home? How do these two companies make money?
