Yesterday, Google announced that it is rolling out Google Now to its Chrome browser. It may take a while for it to make its way to you, or you can manually enable it now by going to chrome://flags and enabling Google Now notifications.
For those of you that don't use Google Now or don't know what it is, you're really missing out. If you are a user of Google services (mostly Gmail and Google Search), and own a smartphone, it's a great tool. It's basically predictive, real-time notifications based on your search history, location and possible email history. If you have a flight coming up for which you've searched on Google or received a boarding pass through email, Google Now will display a card with details of the flight and its status. It will tell you real-time traffic info on how long it will take you to get home or to work from your current location, display local weather, tell you the sports scores of your favourite teams, and much more. It's built into Android and is part of the Google Search iOS app. The Verge has some good coverage of the service here.
