So to me there's two parts of introducing new technology that every group has to address: the technical advances and the policy around the new technology for consumers. Amazon is obviously doing a good job to help the technical side of it, but so far I think they're failing on the policy. They haven't mentioned the ability to shut off the split processing or use a different browser, and the answers to their privacy FAQs on privacy on their website are totally evasive. I think they're going to find themselves in a world of hurt if they don't start being more open about their policies, but who knows, it may end up not mattering to the masses.
