I take issue with the problem statement: "today, phones are built around tasks and apps. To see what's happening with your friends, you pull out your phone and navigate through a series of separate apps."

Firstly, the value to me in owning a smartphone and paying the charges associated with it is ultimately task orientated - from running my business, to getting driving directions, to wanting to play a specific genre of music at the gym. That's actually where the value is in my phone. Maybe I don't fit the demographic, but I don't want those to become second-class citizens over friend communications.

Secondly, it's very hollow to define the problem as 'your friend's activities are spread across multiple apps' when their solution only promotes Facebook activity to the fore.

My FB friend's activity is currently only contained in one app - the FB app. Their solution only removes the checking of multiple apps because those other apps (non-FB social networks, IM networks, etc) are going to be relegated into obscurity and no longer top of mind.

How's that ultimately helpful to my real, technology agnostic, friendships?
