Re: ...nobody seems to care about the privacy aspect?...
It's GOOGLE. They make their living by violating our privacy in every way possible and selling the info they get. They care a lot about stripping that privacy completely away and monitoring our every move.
The stated goals are just a cover rationalization, like "terrorist" for repressive surveillance. Personalized search. Locks that recognize faces. Android OS. Whatever they say the reason or "benefits" are, the customer for whom the product is designed is Google.
Not us. We're just the sheep to be fleeced.
