From the article: "The problem of app discovery is not one to be overlooked.
To take an example , sorting through and finding the app you need from over 425,000 available on the iTunes store is a herculean task.
Add in the problem of gaining customer interest and you have another big task on your hand.
...
However Intel does have one trick up its sleeve and this just might be a game changer.
The idea here is to allow consumers to build their own sub app-stores.
Curating the best of apps from a particular genre and creating a sub app-store would let users with a specific interest find the top apps with ease.
So it will be possible to have sub appstores with special focus on music apps , medical apps and so on."
