Ah, thanks for the followup. So basically the point is that people are recognizing the problem isn't just a growing pain of early mobile adoption, but rather is a serious and fundamental problem that needs lots of money and effort to tackle (but which offers correspondingly massive rewards, they expect).
This article puts into perspective why this could be a potentially huge strategic play.
