I was indeed very suprised about the last changes on the App Development from LinkedIn and Facebook Messenger. Both products developing a richer and greater user experience. Showing that the mobile OS is only a dimension of the user experience. LinkedIn has shown up with a perfect new GUI. Facebook Messenger drives more fun into instant messaging than ever before. Google has launched shortly Google Now with a enriched search experience and I am looking forward to see their way of Messaging with Project Babel. And Facebook Home is a way to shift the OS/Android plattform on a second level. BTW: did you see the new Yahoo weather App? All these examples are just a taste of what is happening in the Silicon Valley and other innovation hubs.
