In mobile this is quite different: nothing is settled. We have the web and apps and of course app stores, and then we have many complications - voice, in-app payments, web apps, hybrid apps, widgets, push notifications, social messaging apps, Google Now and Siri. Then there’s the hardware layer - images, barcodes, NFC, bluetooth, location, motion sensors etc. Innovative and disruptive new interaction models can very often find a route to market, far more easily than they could on the desktop internet. Sometimes, they scale to a hundred million users in a year to two. And we have more and more waves of innovation coming, with things like local wireless from Apple and deep linking to within apps from Android, and a very fast-evolving social messaging space, and more things in 2014 and beyond.
