Google has been releasing some great ads for its products in the past couple of years. The ads for the Nexus devices in particular have been very good.
The latest in these series of great ads is this new one for the Nexus 4 that was aired during the Grammys. Although the ad is for the phone, it focuses solely on the Google Now functionality on the device. You basically see people around the world using the feature for things such as checking the weather, train timings, restaurant recommendations, text translation, flight timings, etc.
