With the current stats on mobile data consumption, its clear people are relying on their smartphones for a large part of their content consumption. Critical information IE timely and relevant information such as planning an evening out requiring multiple sources to complete seem to be finally consolidating. I do not believe its feasible to have mobile screens with endless pages of apps or for the more organized to have many folders of categories. Mobile developers know the value of acquiring real estate on peoples devices, but at what point does it become too much.
Que companies such as Vurb (see http://techcrunch.com/2015/02/26/mobile-search-david-vs-googliath/) . I believe this is the future. Consolidation, easy, bite sized content pieces coming from multiple data sources. Google Now is a great passive example of this by integrating with Gmail and pushing relevant content such as local weather, daily commute info, expected package arrivals, stock prices, sports team news etc.
Vurb is aiming to make mobile search more user friendly by creating a simple path with a few taps to get users what they need and plugging into multiple partner content such as Yelp, Uber an Rotten Tomatos to provide a quick, seamless process to get users what they want in the least painful way.
Cards are becoming more and more important and I believe with the amount of information being spit out at people on a daily basis, the only way a person can consume ala Twitter is through bite sized Cards. (see: http://techcrunch.com/2015/02/27/cards-transforming-web).
