Interesting reading, what I am struggling to find is any behavioural statistics. What are people doing when on the web/ app on a mobile? Predictions of users/page impressions is useful but the long tail is surely how people are using these websites, are the majority just browing, what are they doing when they go to the top mobile optimised sites such as Facebook or Amazon. Are there differing user experience patterns emerging due to the unique capabilities of the devices...etc.. Are we seeing a rise in purchasing through a mobile, how are people using apply processes when on a mobile...with this information you can start to understand the "need", predict to a better level what the true demand of certain processes are likely to be and contribute to design definitions with a greater level of clarity. I have seen similar metrics for internet but not specifically for mobile... should we not be past the point of looking at just the what and how many but starting to focus on the how?

Understanding how someone is using something..now that is powerful information!!!
