Same will be soon replicated into the Laptops and other computers.
And last of all the news of Google dropping the bombshell. “The company demoed a new feature within its Android OS which allows the Now service (a dashboard of notifications focused on your life and interests) to plug in as a layer that essentially hovers above any app running on your phone or tablet. Activated by the home button, it’s always there. This means that you can get contextual search information around almost anything you’re doing, provided there is text and data that Google can pull from the app itself. And the best part is that developers won’t have to make any changes to their existing software to allow the new service — dubbed Now on Tap — to bring search and context into the user’s view.”
