Google Now knows what we want before we do - Business - The Boston Globe

Concluding paragraphs of a Hiawatha Bray review

"Google itself is certainly a data hog, a repository of detailed data on millions of us. This has mainly benefited Google, which earns its billions by targeting us with personalized ads. But with the new version of Google Search, users get the payoff.
Google Now’s customized information feeds know our wants before we want them ourselves; Google’s voice search feature captures our questions the moment we speak them and responds almost as fast. Combined, they smarten up our smartphones in ways that Siri can’t match."
