Google just keeps on closing the gaps between its products, as today we're seeing that the Chrome team is getting ready to put Google Now into the Chrome browser. An eagle-eyed user spotted code being merged into the Chromium project that is "creating a skeleton for Google Now for Chrome implementation." We'd expect to see more being put in as the feature gets closer to a true launch.
We're not so sure how the concept of Google Now fits into the browser, but it will be interesting to see how it ends up being implemented. Surely as devices like Chromebooks become more widely accepted -- many of which have 3G data access -- something like Google Now makes sense on more than just phones and tablets.
