Where's the mobile content now?

So I got my latest newsletter for Mobile Content "stuff" and there's another crazy statistic:
Mobile data revenues will increase by a compound annual growth rate of 16 percent from $24 billion in 2007 to over $100 billion in 2017 according to a new forecast issued by financial intelligence firm SNL Kagan, which cites the recent launch of Apple's iPhone 3G and other new smartphones as the catalyst behind the expected surge.

So it's interesting to see how iPhone has helped push mobile content. The UI is fun and easy. However, developers are still struggling to gain access to developer tools that actually work. A device is only as good as the applications that are available to the user, right? or am I crazy?
